Rated 5 out of 5 by Plantguy Very easy to use no adjustments
Reliable tank heater used them for years on simple tanks since no temp adjustments can be made but great product if don't need any other temp besides 78 degrees which is good for most fish nice to not have to worry about readjusting temps or the bigger fish bangingf it around and changing the temp with out u knowing great little heater

Excellent choice for my 10 gallon QT/fry tanks. Let it acclimate to the water temp, plug it in, and walk away. Simple, economical, reliable!!!

Rated 5 out of 5 by haywoodjabloomee works well within its limits.
these heaters are awesome so long as you use it within its limits? 100W for a 30 gallon is a stretch. 20 gallon absolutely. but i live in the cold northeast so i always go with a larger heater. i use these in sumps as backups to main heaters, and for the price i also use for emergency heaters. i always have 2 on hand. will hold temperature(when coupled 2 together) in my 180 gallon tanks till i can get to store for replacements. .have them in my kitchen betta tank on up to a 40 gallon feeder tank. economical, automatic, submersible, small... in a word AWESOME...
