What we liked
- + External controller sets the temperature and shows the current water temperature on a digital display
- + Safety features include low water level shutdown, overheat protection and an error code alarm with a beep
- + Compact 4 inch long element mounts vertically or horizontally with two suction cups and hides easily
Trade-offs
- - Rated for 5 to 10 gallons only, so it is undersized for anything larger
- - Must stay fully submerged and be unplugged about 15 minutes before water changes, per the listing
