Working great to keep 130 pound tortoise at the correct temperature
Had it for a week now and no issue . Box had clear instructions on the inside showing how to set temperatures on ether hot or cold devices. Haven’t yet messed around with the built in alarm so I cannot say anything about that. Only grievances is that there is a small audible pop when the device turns the power on and off to the device : and that there is no way to dim the lighted numbers at night so it does make a small amount of light at night .
I would recommend this to any small animal or reptile parent! This product does exactly what it states and does a fantastic job of keeping my hedgehog warm in his enclosure! 10 out of 10 gold stars
It sure does the job well and makes sure the tank doesn't overheat. The thermometer is just underwhelming and needs to be constantly readjusted into a proper place. it works fine but is easy to dislodge and move around. Fell into the water bowl one time.
It's a thermostat - the sensor has an incredibly long cord so you can really put it where you please. The device itself is really self-explanatory and took me no time at all to set up for my critter area.
