Sofia X. ★★★★★ Oct 21, 2026

The thermostat keeps my 10-gallon tank dead steady at 78°F—I checked it against a separate thermometer for a week and it never drifted more than half a degree. Compact little unit that's easy to hide behind the filter, and it's been running quietly for two months straight.

Set it up in my nano tank and the temperature hasn't fluctuated once, even with the room cooling down at night. The compact size is perfect for tight spaces.

Works perfectly in my 5-gallon tank, the compact design fits easily in tight spaces without overheating. I've had zero temperature fluctuations since setting it up.
