FREESEA First Impressions
7L Imagitarium tank.
I use a 50 for a 5 gal and a 10 gal tank. I used to try those other cheap heaters sold on amazon. I will be ordering more of these in the future. Temperature is slightly off by running a little warmer. I adjusted the set temperature a little lower to be more in the range I wanted. Easy enough to let it run all the time. It comes with a hanging kit and can be secured on the edge of the tank.

FREESEA Final Thoughts
Highly recommended.
So when I first received it it didn't work and I was very disappointed. The temperature gauge is fairly accurate in my 55 gallon tank. I will definitely be buying another one for my other tanks at bigger one. I have it set to 81F to get a 77F water temp. I have had to turn the dial to about 78-79 for the tank to stay around 76 degrees. The heater is being used in a 40 gallon breeder. The bonus digital thermometer it came with has been super helpful, and is accurate.
