Sophia S. ★★★★★

Took a chance on this for my reptile enclosure, and the relay click is satisfyingly precise. The sensor probe reads within 0.3°C of my digital thermometer, which is impressive for the price.

Andrew ★★★★★

The little screen is bright enough to read across the room, and the buttons click with a satisfying snap when I’m setting the target temp. Wired it into my reptile enclosure’s heat mat in about ten minutes and it’s been holding within a degree all week. Hard to beat for the price.

Scarlett ★★★★☆

The programming interface isn’t the most intuitive, but once I figured it out the temperature readings are very accurate for the price. I’m using it in a small fermentation chamber and it’s running my heating pad flawlessly.
