The Etekcity Lasergrip 800 outperforms the Lasergrip GM400 in the ice test, receiving a score of 6.6 in this test versus the GM400’s 2.9. It also does much better than the GM400 in the oil test with a score of 7.3 over the GM400’s 6.96 — it’s close, but still not quite as high.

The Etekcity Lasergrip 800 offers a superior design in all aspects compared to the Lasergrip GM400, with a total design score of 8.0, while the GM400 only received 6.1 from our reviewers in this section.

While both thermometers lack measurement modes, the Etekcity Lasergrip 800 has no audio cues, whereas the Lasergrip GM400 does. This is why the total usability score of the Lasergrip GM400 is slightly higher at 4.3 versus the Lasergrip 800’s 3.75. But, as you can see, both models still leave a lot to be desired in this section.

For those seeking a better design and performance, the Etekcity Lasergrip 800 is the clear choice. However, if you prefer something that’s a bit more intuitive to use, the Lasergrip GM400 might be preferable with its audio cues.
