sach: Very accurate and easy to read, and a great deal for the price. A must have for every aquarium hobbyist.

Trudy D.: the magnet is easy to install and move around. to clean I simply turn it around (both pieces) and my Plecos and snails clean it up by the next morning.

VTer: After going through stick on strips and digital read out thermometers and getting wildly incorrect readings, I decided to give this a shot. I was worried the magnet wouldn't be strong enough to hold up to my very active turtles but so far it's staying put. I'm thrilled that the thermometer that actually works was so inexpensive!

AshAsh: When I started up this hobby, I would get fancy digital thermometers, but they were really annoying since the suction cups that came with them would always come loose, the cables for the sensor that goes into the water were always too long and were an eyesore. The worst part was if they weren't inaccurate when I first started using them, they would eventually become inaccurate.

Eventually, I transitioned over to these and haven't regretted it at all. They don't use suction cups so I don't have to worry about them falling off the tank, and since there are no electronics to it, I'm less worried about inaccuracies. They're also not too big so it's not really an eyesore.

CajingoCajingo: The media could not be loaded.  Sticks fine in the plastic bucket you see in the video and picture, so I know it will stick find in the aquarium when I get ready to use them. I know the results will be a bit different in the 20 gallon aquarium compared with this little one gallon bucket. But this thermometer matched temps with the other 2 nonetheless, so I will have confidence with it in my aquarium.

paul: great concept unfortunately thermometer is out by 2 degrees

Anonymous: Realized that my more expensive electronic thermometer was off by 6 degrees, so I tried this more conventional thermometer. I'd have some in the past but hated that the suction cup would stop working over time, so this magnet application is wonderful. Accurate within one degree F, which is more than I can ask for to keep my bettas healthy and warm.

AndreaAndrea: Was indecisive in buying this since I didn’t know if the numbers were going to be accurate, but I don’t regret it!
Love how it’s big enough to read the numbers and that it’s made out of plastic! Also, it’s the perfect medium size!
It did came a little dirty in the magnet part, but you can’t see it once you cover it with the other magnet.
Will definitely be buying a heater next for my aquarium now that I know the water temperature!

Kim T.Kim T.: This a great little thermometer. It is about 6 inches in length and roughly an inch wide. The white background color makes it easy to read the contrasting black numbers/temperature. The magnet is a terrific feature that allows you to easily move it around when cleaning the aquarium glass. It also maintains contact between the two pieces well enough that it doesn't disconnect when moving it. I have mine on my 60 gallon cube marine tank. I double checked the temperature with another thermometer and it was spot on the same temp.

I liked the first one so much that I just ordered three more to go in other aquariums. However, as you can see on the second photo, the glass on one of the three was broken on delivery. (Please note, I do not believe this is directly related to the quality of the product.)
