Review: Little beta blanket - This thing works like a charm! Just plug and play. Ever since I put it in my Fishtank, my little beta fish are so happy and warm. It’s automatically controlled by the thermostat set at the factory. I was a little freaked out at first when I thought of the idea of buying something that was controlled automatically, but no boiled fish yet! They’re warm and cozy and happy. If you’re on the fence about buying this for your beta fish, look no further than this heater. Buy your little beta fish a blanket before they freeze to death. I’ve been using it for about three months now and it’s held up so far. It’s the perfect size to fit into a 3 gallon aquarium.
Review: Perfect! - This is perfect for my 3 1/2 gallon beta tank! Keeps it the perfect temperature for him. His name is Gill.

### ⭐ Should've got something else
*by T***T on August 23, 2023*

Edit: It died right at a year in another tank(couldn't let it go to waste). Fluval wants me to ship it on my own dime and pay for return shipping. So it's cheaper to buy a brand new one. Consider this when thinking long term about this heater. First off, I got a DOA. This isn't a big deal, but I should mention it out of the gate. That said, I really do love Fluval products. The heater was purchased for a Fluval Evo 13.5 to replace the glass one that's too long. While the heater is really compact, the suction cup is useless after a week. So it will fall down on top of the return pump. This warped the case of the pump a bit and made it hard to take off and on. I ended up rigging it up with the power cord to keep it from doing more damage. It keeps the water at 80-82°F (26.6-27.7°C) which is really warm for most aquariums. There's no way to change the setting. It will sometimes decide not to work dropping to 72°F (22.2°C) or work too well and jump to 84°F (28.8°C). It may do this in a single day too. This creates a really harsh environment for anything but some hardy fish. Which stinks as this is supposed to be for a nano reef tank. All in all, with the first one being DOA, a suction cup that's worthless, and the simple fact it doesn't do its actual job well I had to rate it a 1 star. I ended up with a non-Fluval brand and now can't be happier.
