Coralife Digital Thermometer - Accurately Monitor Aquarium Temperature

ashley: I've bought a few of these and will continue to buy more -- fast, accurate, and easy to read.

R: Barely used it when the numbers started fading and kept turning on and off on its own. Possibly something to do with the wire. Bought this for $10 and too late to return. Bought the HDE 2 Pack LCD Digital Fish Tank Aquarium Thermometer Terrarium Marine Temperature (Black) instead ($4.99 for 2 thermometers + $4.99 shipping) which I have no problems with so far.

Cornelius Benedict: Pretty good thermometer, reads the same as my others so it must be accurate. Only downside is it has a weird hole in the back for what looks like to fit a screw head for mounting it, the suction cup end doesn't fit inside of it. Chord seems frail. It's ok for the price though.

BREAVIELL: I'm very pleased with this product. I bought 4 of them. Exceptionally accurate to within a degree either way. Price is obviously very attractive. I've left them turned on all the time. Doesn't seem to be a heavy drain on the battery at all.

Carl Konosky: It gives me a temp.. and it is fairly accurate but the battery wouldn't stay in place so I had to take a piece of plastic and shim it in place so the unit would stay on with my second one, but my first one didn't do that. Its been a few months now and I leave it on constantly so the battery life seems fine and the suction cups hold pretty well I haven't had too much of an issue with them constantly falling off or anything. it gets the job done but its not high quality.

A. Jones: I use this thermometer on all of my nano tanks. It's compact, easy to install, and easy to read. I bought the first one a year ago, and have since bought two more. It seems to be pretty accurate. I ran one in my 55 gallon for a couple weeks alongside my temperature controller and it consistently provided the same results. The cord is long enough to use in a bigger tank, and is thin enough to roll up and tuck away on a smaller tank. I've been really pleased with it and will continue to buy them.

David YS: Good price, battery lasts a while.

++++
Compared with an analog thermometer and temperature reading was accurate. Long cable

------
Suction cup on the sensor becomes stiff after a couple weeks, and does not stick to glass anymore.

Rick: I have no problem with the retailer I purchased the thermometer from. What I do have a problem with is that I have several similar products, digital thermometers with probes like this one, and several other types of thermometers that all agree within a few tenths of a degree. This one is off by as much as 5 degrees at any given time. It reads lower than the real temperature when the real temperature is under 70 F. It reads higher than real temperature as you go above 70. Perhaps this is a problem with the C to F conversion? I don't know. What I do know is that a temperature probe for terrariums or vivariums, whatever, should not be made of black plastic. That's the worst color and the wrong material. The probe should be reflective or white. Not flat black. If you're looking to save money, Do yourself a favor and spend a bit more for a better value.

A. Goldberg: I've had the thermometer in my tank for a couple of weeks now. Right out of the box, it was easy to set up. It comes with a really long cord on the temp probe, which for me is a little excessive. But there are two suction cups to help with cord management. So, you can position the probe exactly where you need it. Beyond that, it's just a basic thermometer, which is just what I wanted. I was tired of watching my little LCD gauge slowly peel off the side of the aquarium, and this is the perfect affordable solution. The other benefit of the portable nature and the long cord is that I can test the temp of any water I'm putting in the tank. It's often too cold or too hot coming out of the faucet; now I can get it just right before I do my water changes. I can't speak to its accuracy, because I don't have another to compare to, but it seems about right. All in all, a good purchase.
