Our Verdict
Receiving one of the lowest sous vide scores in the group, the Gourmia GSV115 certainly is not our first choice in the fleet. This product did exceptionally poorly in our circulation tests, wasn't particularly fast at heating up water, and scored below average in our accuracy assessment. It did keep a very constant water temperature, but this wasn't enough to redeem its otherwise lackluster results compared to the other appliances.

There was only a single one of our tests where the Gourmia delivered a particularly noteworthy performance in sous vide testing: temperature stability. This sous vide delivered an essentially perfect performance by maintaining a steady temperature within 0.1°F over 60 minutes.

Besides that, this product's interface and clamping system aren't amazing, but they are perfectly passable. The touch buttons are decently responsive, but the controls aren't terribly intuitive, forcing you to hit the key with a “play” symbol to start it heating and to start the timer counting down once the water is preheated.

It has the typical screw action clamp mount, but it doesn't spin freely, so it can take a bit longer to get it mounted securely than other products.

Dislikes
The Gourmia scored average or below in the remainder of our tests. It didn't heat water or recover its set temperature very fast, taking 56 minutes to heat water to 147°F when other sous vides could do this in under 40 minutes. It also wasn't super accurate, with an average error of 0.89°F under when the temperature was set to 135°F, and 1.12°F under when it was set to 147°F.

The Gourmia also delivered an uninspiring performance in our circulation evaluation. In our dye test, it was one of the slowest to integrate all the dye into the water, taking over three minutes. The fastest models did this in 15 seconds or less.
Should You Buy the Gourmia GSV115?
All in all, we didn't find the Gourmia GSV115 to be one of the best sous vides. You can use it for cooking a tasty meal, but it pales compared to other models that cost less and are considerably worse than other products that don't cost much more. We would suggest you check out alternatives to this product. To be fair, it did cook more than acceptable meals on many occasions, but it can't compare to the premium models. It's one of the least expensive models we tested, but it also delivered one of the lowest scores.
What Other Sous Vide Machine Should You Consider?
If price is the reason you considered Gourmia, we get it. Given the lower performance of the budget options, it can be challenging to find an excellent choice for a lower price. To find a reasonably priced selection with impressive test results, we recommend a product that costs almost twice as much. The best value sous vide is the VPCOK Sous Vide Cooker. With better temperature test performance and being easier to use, we think it is worth spending the extra money to avoid the frustration of a less expensive product.
