Good easy and quick
These have now been working well. I think the glass interferes and gives a slightly lower temp than what is in the tank. However they are consistent in their readings just add .5-.8+ and wonderfully easy to use Read more

Customers find the thermometer accurate, working well on the outside of tanks, and consider it worth the money.

I love it! its super small and its very accurate its definitely a good price, it comes off pretty easily and it sticks on really nicely, I definitely recommend this for a fish tank or marimo tank. Read more
Works great, bought 2 and they read a steady temp across my 125 gallon tank. Bright and easy to see Read more
I am very pleased with this product except for 2 issues. This seems extremely accurate and does what it says to do. The display is clear and is fast updating itself on the temperature of the aquarium. It is very responsive and you can’t beat the price of only 6$. The adhesive isn’t strong but it’s enough to keep it and Measure temperatures. This actually ended up to my advantage as I had to return my aquarium and I recycled this thermometer with great ease Second, the power button part of the thermometer seems to stick out a bit from the housing. But it seems to be holding together after a couple months. I’ll use it until it doesn’t work anymore and then I’ll go to the Paizoo brand as it is much better built and is only two dollars more.

Love this! I have a heater but it doesn’t tell me the temperature of my tank. This lets me know where things are at which is helpful during winter months when the heater struggles to fight against the chilly air. My recommendation would be to make sure you are happy with where you are putting it because the adhesive works FAST. Before fully pressing down, I realized it was a bad idea to put it at the top of the water line but it was too late to remove it. 100% worth the money. I’ve had for a few months and haven’t notified an issue with the battery. Read more
I own 3 of these thermometers and they’re all super accurate. Thanks to these I learned my heater was off by almost 5 degrees. Super great deal! Will buy again Read more
I really love this thermometer because a traditional thermometer is difficult for me to read, even with my contacts. You just stick it on the side of your tank and push the button when you want to read the temperature in your tank. It seems accurate - the temperature might fluctuate by a half degree, which makes sense due to the cycling of the thermostat. It is attractive. I recommend this and will buy again when I get another tank!! Read more
I use this for my frog's aquarium, it's accurate and works great! Very simple setup, you just stick it on to the outside of the tank. Read more
