Review: Stable and works extremely well - My tank that I'm currently cycling was hitting 90° where I live in Jamaica. I originally wanted a betta fish to inhabit my 5 gallon fish tank, but I knew it would not survive in such high temperature. I started searching and searching for something within my budget (since i had more to get for my fish tank) and came across this. I bought the dual fan version since i wanted the most i could get out of it. I would've gotten the triple version but i would not have the space for it. My hopes were hanging by a thread but this thing surprised me. The first night i tested it out, the temperature went from 90.5° to 81.5°. It was just enough to keep the water cool and I am grateful. During the days when it's extremely hot (summer in Jamaica), it obviously gets a bit warmer, but it's on the bridge between 82° and a little over 83°. I think my future betta will be able to live with the slight higher temperature (fingers crossed). I just know it's definitely an improvement compared to 90° up. Btw, it's a fan so you will hear it. I use mine on the higher speed, yet it's not too loud but it's not silent. I use a fan for myself regularly so the sound of this fan is overpowered which means it doesn't bother me. For other people who are sensitive to sound though, it's up to you if you can put up with it for the better of you aquatic pets.
Review: It works great! It won’t fit a rimmed aquarium - I was pretty skeptical about these little fans being able to cool a tank for an axolotl but they totally work! I have 10 gallon and 40 gallon tanks set up with the 2 fan option. The fan on the 10 gallon can achieve almost 9 degrees cooler than room temperature and 5 degrees cooler on the 40 gallon. I was really impressed that it still worked on a much larger tank! And I am using the lower setting on the fan. The humidity currently is 50% (inside) and my home is around 70 degrees. There is a good amount of evaporation so topping off the tanks with water daily or every other day is a must in my conditions. I have only had these for a couple weeks so I don’t know yet how they hold up. Given the price if they work for a year before they break I won’t be upset. As many others have mentioned, they won’t fit your rimmed aquarium. But you could carefully remove part of the rim (watch YouTube how to) or devise a way to rest it safely over the water. It would be great if one of these fan vendors read that these don’t fit rimmed tanks and adjusted the design- it’s only off by a tiny amount.

### ⭐⭐⭐⭐ Only fits onto raw glass
*by M***Y on July 8, 2024*

This fan seems quiet and helps move the air across my water surface to keep it a few degrees cooler. I wish they made it to fit a tank with a rim as MOST aquariums have that and it's just teetering on the edge balancing in a most precarious situation! It has fallen into the water a couple of times but continued to work and didn't cause a situation. I hope they will consider this issue in their design. Many people have complained of this one issue.
