It works

First time I used it temp went above 80. I had it set at 76. Turned it off, let the tank cool down, restarted it. Seems to be working fine. Maybe I didn't read it correctly,
All good!!

I've been using this heater for 4 months now. I wanted an adjustable heater since I keep my house cooler. I wanted to keep my tank on the cooler side of ideal so that the tank isn't heating my house. My only real complaint about the heater is that the bottom cap kept falling off. It's just a plastic sleeve. I took a silicone one off an old heater that I was tossing and am using that instead. Really, the cap isn't necessary unless you're worried about the glass banging into stuff. The clips are holding well. Make sure you are clipping near the light and above so that the plastic isn't in contact with the heating element at the bottom. Temperature of the tank has stayed consistent. Oddly, even though the heater is black, when it is submersed, the top becomes a light gray. I wish it was black, but that doesn't affect how it works. I would be happy to buy another one if I needed to for another tank.

Use this for my betta to help keep his water temperature where it needs to be. I would give it a 5 but I had to mess around with it to adjust the temperature
Great product
