Build Quality
Overall Design Scoring

The Cosori CO130-AO has a lot of design features, all of which are of high build quality. A few that stood out to us were the clear LED display, powerful convection system, large cooking space, high power output, and handy accessories like the rotisserie kit and air fryer basket. If we were trying to be nitpicky, we’d say the interior can be improved with a non-stick coating like the Breville BOV845BSS.

The design of the Hamilton Beach 31127D is basic with a simple stainless steel exterior. The oven has a similar capacity as other medium-sized toaster ovens, with greater length and width but less height. Its roll-top door is a unique feature that we found useful.

Usability Comparison

User Control
Ease of Use
Overall Usability Scoring

A well-designed automatic preheat phase, simple toggle options, and practical cooking functions gave the Cosori CO130-AO a good score. The cooking chamber as well as accessories could have better coatings to make them easier to clean, though. As an additional minor inconvenience, the oven doesn’t have a pause-resume mechanism upon opening and closing the oven door.

Although the Hamilton Beach 31127D doesn’t invest much in convenience, it also doesn't pose any problems. You may not be able to select an exact time and temperature with the analog control knobs, but realistically, you don’t lose much precision.

Overall Performance Scoring

The Cosori CO130-AO, on average, performed great throughout all of our tests. It made full use of its high power output of 1800 W and its powerful convection system. To us, these were some of the main grounds for establishing the product’s value for the money. The included rotisserie kit and air fryer basket were also very helpful in our Whole Roasted Chicken and Baked French Fries tests, respectively.

The Hamilton Beach 31127D did a good job at making toast but struggled with french fries. We suspect its 1400 W power draw isn’t sufficient for its capacity, so it couldn’t quite maintain high temperatures. Of course, the lack of a convection system didn’t help either. A more preferable but still affordable choice could be the Toshiba AC25CEW-BS.

The Cosori Air Fryer Toaster Oven (CO130-AO) completely mopped the floor with the Hamilton Beach 31127D Countertop Toaster Oven. Nonetheless, the Hamilton is still a solid choice if you want an inexpensive medium-sized unit that doesn’t have convection.

Design-wise, the Hamilton has a good overall build quality encompassing its roll-top door that moves out of the way while you bring food in and out of the oven. Its control dials are also very precise for being analog.

The Cosori, on the other hand, has an intricate control panel with an informative digital display, intuitive buttons, and toggle switches for convection settings, lighting, and temperature conversion. On top of a larger capacity, these features, of course, make the Cosori cost more than the Mueller.

Performance was what really separated the Cosori—our best-to-buy pick—from the Hamilton. Thanks to its convection system and higher power draw, the Cosori consistently produced top-tier results in toasting bread, baking pizza, roasting whole chicken, and air-frying fries. The Hamilton’s foods were above average and thus, couldn’t compare with the Cosori.
