BELLA 13991 Classic vs Oster Belgian Side-by-Side Comparison




Our Verdict
- Performance (50%)7.0/10
- Design (20%)7.8/10
- Ease of Use (30%)6.8/10
- Performance (50%)6.0/10
- Design (20%)6.2/10
- Ease of Use (30%)5.0/10
Bella has built the 13991 Classic as a “budget” flippable Belgian waffle maker. And, according to our tests, it’s excellent at what it does. It belonged to the higher percentage group in terms of performance. It was able to bake some truly delectable waffles with superb coloration, spongy-soft texture, and flavorful taste. Although its build quality left much to be desired, it’s undeniable that the Bella 13991 Classic is a decent choice in the price range.
However, the price range of the Bella 13991 Classic may still be too high for some people.
That’s where the ultra-budget Oster Belgian waffle maker comes in. It stands as a far more affordable option than the Bella. But be warned of the trade-offs. Its performance is among the lowest in our database so far. Combine that with the inferior build quality and an inadequate safety score; it may be worth splurging on the Bella.
Bella Rotating Waffle Maker’s Performance
- Self-Mixed Recipe (50%)6.9/10
- Birch Benders Mix (50%)7.2/10
- Self-Mixed Recipe (50%)5.2/10
- Birch Benders Mix (50%)6.8/10
Self-Mixed Recipe





- Heat Level: Maximum
- Cooking Time: 7 minutes
The coloration was decent despite the waffle’s wells looking slightly burnt, and some spots on the crust looked undercooked. It received only a passable grade due to having a low aeration rate. Fortunately, it picked up the slack with its tastiness.
Color (6.25) — 35%
- Color tone: Very dark brown - Light brown (both)
- Color distribution: Even
The crust was a bit dark, but there were no signs of charring. Dark spots mostly focused within the wells of the waffle. Outside the wells, the waffle mostly had a pretty light brown color.
But since it was darker than ideal, we couldn’t give it a higher score than a “good” 6.25.
Texture (6) — 25%
- Texture: Mediocre
- Aeration level: Medium; air bubbles have begun filling the interior of the waffle. However, their sizes were small, and their numbers were few.
Air bubbles have begun to fill the interior of the waffle. Unfortunately, they haven’t developed to their full sizes just yet. All the bubbles we saw were small, concentrating mostly near the crust, while the core of the waffle was dense.
Taste (8) — 40%
- Flavor: Sweet with a buttery aftertaste
- Mouthfeel: Slightly mushy
Our chef rated the waffle highly, citing its sweet flavor and buttery aftertaste. And though the mouthfeel was a bit underwhelming, it didn’t seriously affect the waffle’s quality.





- Heat Level: Max
- Cooking Time: 5 minutes
The Oster didn’t do well in our performance test. The coloration of the waffle—with its blotchy, charred crust—was disappointing. Cutting it open, the waffle had a dense and under-developed interior. It translated to an underwhelming mouthfeel in the taste test. And because the batter was only half-cooked, the waffle still tasted like raw batter.
Color (35%) — 5/10
- Color result: Very dark brown - Dark gold (Both sides)
- Color distribution: Even
The waffle’s crust was darkly colored, especially within the wells of the waffle, which had dark brown to very dark brown coloring. Fortunately, while they may look charred, we didn’t see any carbonization when we closely looked at each well.
Outside the wells, the waffle was a rather beautiful dark gold. But it’s still not enough for us to give the waffle a higher score than a five.
Both sides have roughly the same color gradient.
Texture (25%) — 5/10
- Texture: Wet, mushy
- Aeration level: Low
Despite the burnt-looking crust, the interior of the waffle wasn’t as well-developed as we had hoped. Air bubbles were visible, but they were small and few. Furthermore, the waffle’s core was dense and slightly mushy.
Taste (50%) — 5.5/10
- Taste: Bland, bitter at charred spots.
- Mouthfeel: Dry on the outside, mushy on the inside
The contrast between the overcooked outside and the undercooked inside makes for a disappointing tasting experience. There was a hint of the batter’s sweetness and buttery taste. However, the tastiness was ruined by the bitterness of the burnt crust and the egg-like taste of the undercooked core.
Ultimately, our chef rated the Oster waffle maker 5 out of 10.
Birch Benders Mix





- Heat Level: Maximum
- Cooking Time: 8 minutes
In this test, the Bella waffle maker did a slightly better job, but not by a lot.
Coloration is visibly improved with a more even, prettier coloration. Unfortunately, because the waffle is peppered with air pockets, it has several discolored spots. The texture is decent, but its aeration level is still low, resulting in a mushy texture. The mushy texture is one of the reasons why our chef didn't give the waffle a high score on the taste test.
Color (8/10) — 35%
- Color tone: Light gold (Both)
- Color distribution: Even
The crust on both sides of the waffle maker had a beautiful golden-brown color. On the crust were large formations of air bubbles, which had a pale yellow color of undercooked batter. Besides ruining the overall look of the waffle, they also messed with the color palette.
Texture (7.8/10) — 25%
- Texture: Good
- Aeration level: Medium; air bubbles have begun to develop, but they haven’t reached their maximum sizes
The waffle has filled out well with a thick, soft interior. It has a medium aeration rate, evidenced by the many tiny air bubbles within its core. The bubbles were in the process of forming and expanding, but the aeration process was cut short before it could reach completion. Thus, while the waffle was soft and spongy, it was still too moist on the inside to receive a higher score.
Taste (6/10) — 40%
- Flavor: Sweet and slightly savory, cloying in undercooked parts
- Mouthfeel: Soft and spongy for the most parts, mushy in certain spots
As a whole, the waffle’s flavor profile was decent. It had the signature sweet and slightly savory taste of the Birch Benders mix. However, certain parts of the waffle were undercooked and gave it an off-putting cloying taste, which negatively impacted its scoring on this test.





- Heat Level: Max
- Cooking Time: 3 minutes
Although color distribution is uneven, the brighter and more palatable color tones are a big step up. The interior has developed this time, resulting in a soft and fluffy waffle. Our chef also rated the waffle’s taste highly, appreciating its sweetness and velvety texture.
Color (35%) — 6.3/10
- Color result: Very light gold and dark brown (Both)
- Color distribution: Uneven
Coloration is slightly better this time around with the pre-made mix. Unfortunately, the difference between this one and the earlier sample made from our self-mixed batter isn’t drastic enough to give it a significant score boost.
The color tone is better with a nice golden brown shade at the center of the waffle. Surrounding the center is a noticeable “ring” of burnt batter that ruins the aesthetic of the waffle. Out along the edges, the crust there has a light gold of undercooked batter.
It’s because of this unequal distribution of colors is the reason why it doesn’t get a higher score in this segment.
Texture (25%) — 6.5/10
- Texture: Mediocre
- Aeration level: Medium; air bubbles were beginning to form, but their sizes were still small
Texture is acceptable. Despite the unattractive coloring, the inside of the waffle has nicely developed. The aeration process has formed a lot of tiny air bubbles on the inside, creating a soft, fluffy texture. Although it is not excellent, the texture of this one is at least acceptable.
Taste (50%) — 7.5/10
- Flavor: Sweet
- Mouthfeel: Soft, no excessively dry spots
Taste is the best part of this test. Compared to the earlier test done with self-mixed batter, the sample produced with the pre-made mix tastes better, according to our chef. Because there’s very minimal burnt spots, the flavor is sweet without any hint of bitterness. This, combined with the fluffy texture, creates a decently-tasting waffle that comes closer to the “restaurant-quality waffle” slogan that Oster has placed in its advertisements.

What’s in the Box of the Bella 13991 Rotating Waffle Maker?

- Bella Classic Rotating Waffle Maker (13991)
- User manual
- Drip tray
The box includes the waffle maker, a user manual, and a drip tray.

- Oster waffle maker
- User manual
In the box, you get the waffle maker and a simple user manual. There are no extra accessories. This is not surprising considering the budget price point of this waffle maker.
Dimensions

- Length:16.7" (42.4 cm)
- Width:7.7" (19.6 cm)
- Height:7.3" (18.5 cm)
- Weight:5.2 lbs (2.4 kg)
The Bella 13991 is more difficult to store due to its rotating design, which brings its height to 7.3 inches. Fortunately, Bella makes storage less annoying by making the handle foldable. The waffle maker's footprint can be reduced with the handle folded and the body rotated vertically.

- Length:10.0" (25.4 cm)
- Width:8.0" (20.3 cm)
- Height:4.0" (10.2 cm)
- Weight:3.2 lbs (1.5 kg)
The Oster waffle maker is quite compact. Thanks to its size, it won’t take up much space on the countertop, and storage is easy. Notably, you can also store the waffle maker standing upright (vertical).
Build Quality




The Bella 13991's body is made from stainless steel with a mirror finish, which gives it a somewhat premium look. However, we noticed that the mirror finish could be smudged easily and is highly susceptible to scratches. However, a much more serious issue was the extremely loose lid hinge. Whenever it's opened or adjusted, the lid wobbles dangerously.




The stainless steel housing gives the Oster waffle maker a sharper, pricier look. However, the waffle maker’s rough edges are clearly revealed when you scrutinize it up close. Fingerprints can easily smudge the stainless steel surface. Even when you lightly scrape the surface with your fingernails, ugly scratches can appear on the metal.
After a couple of days in the lab, the top surface of the waffle maker lost its original shine. We couldn’t restore it even after several attempts at wiping it down and polishing it.
Like most affordable waffle makers, detailing like the handle, base, and control panel section are made from plastic. They look and feel cheap.
Build quality is poor on the review unit we received. The lid’s hinges are loose and rattle even when lightly tugged. On the backside, we found poorly tooled parts with rough edges, scrapes, and dents. Worse still, the backside of the waffle maker has gaps that reveal its guts, exposing its internal wiring and circuits.
For these reasons, we assess the Oster’s construction quality as mediocre at best and sub-par at worst.
Waffle Plates



- Number of Plates:2
- Grid Pattern:Belgian-style
- Plate Area:44.18 inch2
- Plate Length:7.5" (19.1 cm)
- Plate Width:7.5" (19.1 cm)
- Material:Cast aluminum
- Non Stick Coating:Yes
- Removable:No
- Dishwasher Safe:No
The waffle plates are cast aluminum coated with a layer of PFOA-free Teflon. In all of our tests, the non-stick coating worked perfectly. The waffles slid cleanly off the plates without leaving messy residue behind.
A small anti-spill moat runs around the perimeter of each plate. The moat is too small to catch big spills, which isn’t particularly helpful.



- Number of Plates:2
- Grid Pattern:Belgian-style
- Plate Area:7.8 inch2
- Plate Length:7.1" (18.0 cm)
- Plate Width:7.1" (18.0 cm)
- Material:Die-cast aluminum
- Non Stick Coating:Yes
- Removable:No
- Dishwasher Safe:No
The waffle plates are made from die-cast aluminum. It is imprinted with the classic Belgian-style grid pattern. The total diameter of the waffle plate (with the outer anti-spill moat included) is 7.8 inches. It is able to produce a 7-inch waffle.
According to Oster, the non-stick coating is food-grade polytetrafluoroethylene (PTFE — also known as Teflon), and has been approved by the USDA.
The inclusion of PTFE can be a deal-breaker for many. However, note that, unlike PFOA, PTFE is inert and relatively harmless at temperatures under 400°F. Only when the temperature exceeds 400°F can the PTFE coating become a problem by releasing toxic gasses. During normal operation, the waffle maker isn’t going to come even close to this threshold. Thus, the waffle plates are still classed as safe for use.
The waffle plates are not removable.
Control Panel



- Indicator Lights:Yes
- Audible Alarm:No
- Timer:No
- Browning Control:Yes
The temperature dial turns smoothly but doesn’t have any specific temperature notches or settings. Instead, there are only “Min” and a “Max” labels on either side. The user can tune the dial to any arbitrary point in between.
You will find a red POWER button under the dial, which shines when you plug in the waffle maker. The blue READY button beside it will light up when the plates are thoroughly heated and ready for use.

- Indicator Lights:Yes
- Audible Alarm:No
- Timer:No
- Browning Control:Yes
Though the control interface is barebones, that is to be expected for such an affordable waffle maker. There are two indicator lights. One will glow red when you plug it in (POWER light), and the other green light will light up when the waffle maker is heated to the correct temperature.
Above the indicator lights is a temperature control knob. The knob takes some force to turn and makes a distinct clicking sound as it does so.
Bella Rotating Belgian Waffle Maker’s Power Cord

- Plug Style:Type A (Flat Blade Attachment Plug)
- Length:2.2 ft (0.7 m)
- Cable Management:No
The power cord is relatively short, so you may have to use an extension cord. There is no cable management feature on the Bella 13991.



- Plug Style:Type A (Flat Blade Attachment Plug)
- Length:2.3 ft (0.7 m)
- Cable Management:Yes
The unit’s power cord is short. You will either have to move the waffle maker very close to a power outlet or use an extension cord.
The back foot of the waffle maker has a grommet. You can wrap the power cord around it for easier management and storage. However, since there’s no lock or notch to hold the cord in place, it can unravel easily.
Accessories

- Material:Plastic
- Removable:Yes
- Dishwasher Safe:Yes
A drip tray accompanies the waffle maker in the shipping box. It slides in underneath the waffle maker’s body. The tray does a great job of catching spilled batter. It is removable and dishwasher-safe.
- Material:N/A
- Removable:N/A
- Dishwasher Safe:N/A
The Oster waffle maker doesn’t come with any extra accessories. Once again, at this price point, that’s what we expected.

Handling
It failed the handling test due to the dangerously loose lid. Whenever we started a new waffle, we had to hold the lid with one hand while pouring with the other. If we dared remove that stabilizing hand, the lid had a good chance of snapping shut unexpectedly.
Except for this critical issue, the Bella 13991 is easy to use. The control panel is simple, and the waffle maker turns smoothly. A lock is built into the handle and keeps the lid securely shut when the waffle maker is flipped.
Generally speaking, the Oster waffle maker is easy to handle. Even when it’s heated up, the large plastic handle at the front remains cool to the touch. However, the lid’s hinges are shaky. They make the closing and opening motion a bit awkward.
Safety




- Top Side Temperature:153°F
- Bottom Side Temperature:85°F
- Handle Temperature:90°F
The unsteady lid is a serious safety issue. Fortunately, aside from the lid, we didn’t find any other significant safety problems.
The top of the lid got warm — but not dangerously so — at 147°F.
Both the handle and the base remained cool to the touch. The measured temperatures in these areas were respectively 90° and 85° after several rounds of testings.




- Top Side Temperature:176°F
- Bottom Side Temperature:143°F
- Handle Temperature:189°F
Using a thermometer, we checked the temperature of the waffle maker’s various parts.
The handle was dangerously hot, with a temperature of 189°F. After several cooking sessions, the heat from the heating element and the hot steam raised the handle’s temperature to the point that it could easily cause a burn injury. This is the most serious safety problem of the Oster.
Not just the handle, the control panel area was also piping hot at 176°F.
On the underside of the waffle maker, the front plastic “leg” got quite toasty at 143°F.
So, be careful if you pick up the waffle maker by grabbing the bottom legs. The front part may be quite hot.
The exposed electronics and wiring on the backside could turn the machine into an electrical hazard. A point was further deducted from the overall score.
Cleanability

The Bella 13991 is very easy to clean. Though it’s prone to fingerprint smudges and scratches, the metal surfaces can be cleaned and polished with mild detergent. The waffle plates only need to be wiped down with paper towels every once in a while to get rid of waffle debris. We also don't find it difficult to scrub dried batter off the plastic parts of the waffle maker.
When a spill happens, the large drip tray can catch every droplet. The tray can be washed by hand or loaded into a dishwasher.

The Oster receives a good score in cleanability. Although it doesn't have a drip tray for spilled batter, it can be dealt with fairly easily when a batter spill does happen. Even when the batter dries out and settles on the waffle maker’s body, all surfaces can be scrubbed down easily with a dash of mild detergent.
Indicator Light Visibility



The lights are very dim. It’s almost impossible to see them from afar under harsh lighting. Even with some ambient lights turned off, the indicator lights are still faint.

The unit we received has very dim indicator lights. Under normal lighting conditions, the two lights are hardly visible.
It’s only when we cupped our hands above the lights to shade them from the ceiling lights that the indicators became clear. The lights aren't visible in harsh daylight and studio lights.
