Customers say
Customers find the thermometer easy to use and set up, with good battery life and value for money. The accuracy and functionality receive mixed reviews – while some find it accurate, others report it being inaccurate by a few degrees, and while some say it works well, others mention it stops working properly after about 2 weeks. The temperature readings are also mixed, with some reporting correct readings while others note it reads 2 degrees higher than actual temperature. The durability is concerning as units typically last less than 6 months, and the suction cup quality receives mixed feedback.

Many uses, works great.
These are great. I use them to moniter my outdoor above ground pool temp, my fish tanks and my water cooler bucket temperature my laser cutter too!

Fairly accurate temp readings, calibrated using ice bath
I wanted to see how accurate this digital thermometer was so i calibrated using a ice bath. One of the digital thermometer measured 33.2 F (assuming 32 F for the ice bath). This is fairly accurate since it is +/- 1 off. The other thermometer measured a bit higher (33.7) so they are not the same but close. My el cheapo analog thermometer from APi is more accurate in terms of the ice bath at 32F. But all good since it is within tolerance.

Nice digital thermometers for the price
These digital thermometers are nice for the price paid. They are very compact and easy to read. The only thing I noticed is that it is one degree off, other than that, pretty good and useful for aquarium temperature monitoring.

Great Price and Works well
Great Price and Accurate temperature! Wasnât sure if my dial tank heater was heating accurately, so I got this two pack and they confirmed my suspicions that temperature was too high in my tank!Suction cup makes it easy to stick to the side of the tank for easy viewing! Works in both Fahrenheit in Celsius. Very reliable.

Mixed Feelings
I have really mixed feelings about these thermometers. I wish I could give 2.5 stars. On the plus side – brand new they work really well. They are accurate and easy to use. I use a temperature gun to verify how they are working. They are also inexpensive. On the down side: when they stop working you will still see the temperature displayed but it will be wildly inaccurate. Like 10+ degrees off (always too low in my experience). Even after replacing the battery, they still don’t work properly. I keep using them because they are inexpensive to replace.

Important verification of water temperature
My aquariums hold Sea Monkeys (R) and Giant Triops (tadpole shrimp). The main tank is freshwater. The thermometers helped me setup the hatching tanks and the main tank. Shrimp eggs hatch quicker when the water, light, and temperature is correct. Since the heaters don’t display the water temperature, the thermometers showed how quickly the temperature changed.One unit had a bad suction cup. A deformity kept it from sticking to the tank. Fortunately, a paperclip might work.Seventy-eight degrees is important for life. Make sure your plants and animals are comfortable, too.
