Battery Operated Digital Thermometer

An accurate, long-lasting (4+ yrs) thermometer. Onobtrusive design--both internally and externally. All my thermometers will be digital as a result of how well this one has performed. A bargain.

Great little thermometer. Very accurate, better than the strips and hides well in my tank. I turn it off once I've checked the temp to make the battery last longer.

Works well, cross checked it with a tradtonal type thermometer and this seems right on, only wish it had a back light or some kind of illumination.

After reading the other reviews I am thinking I have the bad one of the batch. Does not give an accurate reading at least 110 degrees out.

Easy to read and install. Reads 2 degrees higher than my floating thermometer, not sure which one is off.

Easy to read and very accurate. I am replacing all my other thermometers to this one.

Great product ,got on time for my new fish tank

Simple and effective. Rapid response time. Great price.

When it works, it appears to match the setting on the heater dial. Sometimes it just flashes random numbers and must be turned off and back on to correct the problem. I personally do not trust it. I am buying something else more reliable

Have had this for a little over a year. Seems to burn through batteries. When it decides to work, it seems to be accurate. power button never worked, so stays on all the time. Should be able to last at least 2 years on a battery, like a watch. I've spent more on batteries than the thermometer :)

I bought several and no two have the same temperature, even when tested on the same tank. A nice design but cannot count on getting an accurate reading.

Bought 6 of these, not from TPP. All 6 read different temps.

Back to glass for me. Even the cheap little stick on color change strips are more accurate.
