    • Works great
Size: No Size
Works great. Does what its supposed to do. Stands straight on its own because its weighed at the bottom with metal balls inside. Just drop it into the tank. My only problem is that its hard to read from certain angles. It tends to slowly turn on its own so it ends up facing another directiong. But is sturdy and pretty accurate. I like it. ... show more

    • A must-have for your tank!

Review Image by Sam Chap
I have a 10 gallon betta tank that I need to keep tabs on the temperature. In the past I have tried the regular thermometers that stick to the side, those suck because after a while they no longer stick and just wind up floating around your tank plus they are hard to hide and an eyesore. I've also tried the sticker thermometers but those lose their accuracy and I do not trust them plus those also do not look great. I ordered this one because I have never tried this kind before and honestly I will never have another type of thermometer. It sinks right to the bottom and stays wherever you put it. I was able to hide mine behind a pot I had inside the fish tank so that I can still read the temperature from the side but from the front view of the tank you cannot see it. Plus I will add that it has been very accurate so far and I also like that the ideal temperature for most fish is highlighted in green. For $2 in change this is a must have for fish tank enthusiasts you won't be disappointed. ... show more

    • Disappointed it stands on the bottom of tank which scare my fishes
Size: No Size
I put it in my fish tank and it sank and stood to the bottom in the left side corner. I was disappointed that it scares my fishes so much that they move and stay at the other extreme right side until I remove it out of my tank. Before I bought it I thought that it would stay on top of the water in the corner which would not scare fishes, but obviously this item has been changed from how it formerly use to work. However the temperature part is readable and supposed to be accurate. ... show more

    • Large and stays upright
Size: No Size
I purchased this thermometer without realizing it was quite large; it stands nearly as tall as my fish tank, which is 3 inches deep. While my current tank is somewhat shallow, this thermometer is essential for monitoring the temperature in a fish tank. The price was excellent, so I decided to keep it and will place it in a larger fish tank in the future. ... show more

    • Quality not so much

Review Image by Amazon Customer
Bought a 2 pack of these. One lasted a month and the bottom broke apart allowing the little weights to scatter on the bottom of the tank. Can't tell if this is molded glass all the way around or not. The piece that broke appears to be glass just not sure how it separated. Not impressed with the quality on these . Definitely made on the cheap side. ... show more
