    Really like it
  

*by J***M on Reviewed in the United States on April 19, 2023*

I like that it keeps temperatures within a range without me adjusting anything. The inner chip manages it from the inside all it requires is plugging it in and placing it in your bowl or tank

    So far so good but suction cup broke after awhile
  

*by E***. on Reviewed in the United States on October 14, 2022*

Great little heater for Betta fish in 2.5 gallon tank. Temperature remains consistent. It’s easy to clean during tank changes. The bottom suction cup broke after several months but the top suction cup is still going strong.

    PLEASE READ BEFORE BUYING
  

*by A***R on Reviewed in the United States on September 14, 2022*

Okay so I saw ALOT of reviews about their fish dying and I was scared at first but I took the chance. I am pretty good with Beta fish now for years and I had a hunch but I wanted to see for myself. Although this product states it can work for a 3 gallon tank DO NOT buy it unless your tank is 5Gallon or more ! It is too powerful for anything smaller. I hope this helps save some fish lives. The decor was really cute and it is a great deal otherwise I have it set diagonal and it’s doing a great job in our AC blasting condo !
