B. Wallace: I've had two of these over the last ten months. The first thermometer started to show inaccurate temperatures after about seven months. The temperature was about 10 degrees off. I ended up replacing this one with the same brand, and the replacement began showing inaccurate readings after three months of use. As of this review, the temperature is off by five degrees, and I am now shopping for another brand.

I was ok with the first thermometer failing. It lasted seven months, and I only paid around $7. I am not ok with the replacement thermometer failing even sooner than the first. So, two stars for not being a long-term dependable device.

DFK: The media could not be loaded.  All of my fish have died. Cichlids, cyps and multis. Could not figure out the problem. This thermometer was working well for the first two months, then suddenly I noticed my water temp was dropping and I kept cranking the heater. Mysteriously, all my fish started dying. Replaced the heater today which has built in thermometer. Turns out it was reading the temperature 20 degrees F less than what it actually was!!!!! Video for proof.

I cooked my fish.

Beng: It is a basic and decent quality thermometer, which worked well for me for about a month. After that it started reading 55.9 degrees F and will not change, confirmed to be inaccurate by two other thermometers, but otherwise functions(turns off and on, changes from C to F). I'm assuming there's damage to the thermal probe, but nothing visible and it seems pristine. Might by again, could be a defect.

Astrid le: I bought this for my fish tank and it works for couple months, but now it won't show the right temp I tried new battery, shutting it off and on, pit it different temperatures. Won't buy again

Sheri M.: After it failed, thought it was the battery. Ordered new batteries. It did not come back on, I switched the reading and it came on faintly. Then completely failed.

Norm Szekely: It is easy to install and easy to use. 4 stars only because the suction cup on the display is hard to stick anywhere. Otherwise perfect. Installation in aquarium super easy, and in the end the display sitting on top is perfectly fine. Recommend for anyone.

RachealRacheal: Seems to be accurate and the size is perfect. Removed one star only because the suction cup that is supposed to hold the monitor against the tank came rumpled and won't stick no matter how much I try it. I leave the monitor on top of the tank lid so not a huge deal but was a little disappointing.
