So far (and I only just finished "test driving" it), I've used it on a 1 gallon and a 2.5 gallon. One thing I noticed is that the "minimum water line" is completely inaccurate. I can only guess that the device's thermostat is located at, or just above, this line. The only success I've seen was a result of leaving the heater completely submerged. That being done, I've had steady 78-degree temps for over a week!
