Works reasonably well in a 10 gallon tank. It may seem to run a few degrees warmer than you set, but that doesn't matter, just turn it down. Be sure to follow the instructions and submerge it to the minimum waterline and let it sit for half an hour before turning it on. Has been working without problems for over a week.
