Compact thermometer

I initially bought this as a back up for another stick on thermometer. It's a great size for smaller tanks and it's easy to read

You get what you pay for

Did not work for me. No big deal my heaters have huge temp readouts and not needed. I never did get a temperature reading

Aqua thermostat

Doesn’t work like I thought it would. Is hard to comprehend. Will not buy another or anything like this one.

Great fish tank thermometer

My fish kept breaking my glass thermometer on the inside of my tank. This thermometer works great and I don't have to worry about my fish breaking glass in their tank.

Happy with this thermometer

I don’t know why there’s so many negative reviews about this thermometer. I’ve used them for years with the oldest still in use being 8 years old. I have 6 tanks. 120 gallon, 55 gallon, 30 gallon, 20 gallon, 10 gallon and a 5 gallon. I have an expensive salt meter that also reads temperature and have checked the readings with this little stick on thermometer. When the stick on reads 79, the meter reads 80. Close enough that I’ll know if a problem arises with my heaters. I find the glass thermometers annoying, hard to read and not something I want in my tank with my 9 inch Tin Foil Barb. I’ve ordered a few more for my newest tanks.

Nonworking

I have the thermometer on the tank and it still has not registered the temp of the water. I do not recommend

They are great

They are easy to put up on the outside. Easy to read. And most importantly, it's not done in Celsius!
