### ⭐⭐⭐⭐⭐ Great small little heater, super easy To use.
*by K***R on November 22, 2019*

I love this little heater, it works good keeps the temperature steady as long as the lid is on, without the lid it does keep it a little on the cooler side but that makes sense it stays about 75 depending on how cold the room is otherwise it keeps it at the right temperature even without the lid. I bought four of these and have them in all my tanks and they are all doing well! I got them when they were priced at seven something and I couldn’t ask for a better heater for the price! They work good and they do what they’re supposed to. They’re small enough that you can put them in a small tank I have one of them in my 2 1/2 gallon, one in my 5 and a half gallon, and one in each of my 10 gallons, and they all work great! The only issue I’ve had with “one” of them is one came unstuck from the wall of the tank once which didn’t matter and all I did was re-stick it.
