The first test shows how long it takes the circulator to heat the water. It went from room temperature to 140°F (60°C) in 31 minutes and from hot tap water to 140°F (60°C) in 8.5 minutes.

We also measured how long it takes to go from 140°F (60°C) to 183°F (83.89°C). This took over 25 minutes. These times put the Kitchen Gizmo near the bottom of the heating tests, which is to be expected with its 800 watt heater, only beating out the Anova Precision Cooker. It generally took twice as long to heat as the Gourmia Immersion Circulator Pod, which is still the fastest heating circulator we've tested.
The Kitchen Gizmo did use less power than many of the circulators, only being edged out by the Joule in power consumption over the first hour.
At 140°F (60°C) the Kitchen Gizmo had a temperature fluctuation of 0.2°F and at 183°F (83.8°C) we didn't detect any fluctuations, which is comparable to most circulators at the lower temperature and tying it for the top spot for the higher temperature. It did come out of the box off by about 1°F, so it was a good reminder that regardless of your circulator, to always measure the temperature independently to make sure it is accurate.
The Kitchen Gizmo did well on the sound test, with results tied for first with the Sansaire Sous Vide Circulator. When measured next to the machine, the Kitchen Gizmo only added about 2 dB above the room noise and once you move more than a foot away the machine didn't show up against the background room noise.
All in all, from a performance perspective it was on the slow side for heating but did good on the temperature variability, power consumption, and sound level tests. At $130, the Kitchen Gizmo is on the less expensive side and comparable to the Anova Bluetooth. It might provide enough functionality to justify that cost, especially since Amazon often discounts it by 20% to 30%.
