Not used yet. I'll update when I get my tank up, but I have the smaller 5w version and it's tiny. This 15w version is surprisingly big, just surprisingly big, but I still like the flat design as it blends more into the background, but I'll have to see how it fares in the aquarium if I have it because of the size get. I'm sure the heating function is good, 5 watts heats my 6.5 gallons relatively easily, never goes out of range and hits 81 during the day but never or very rarely reaches or exceeds 82. that's 5 watts in 6 gallons . So I can imagine that 15 watts in 10 gallons would be a strong motor. I will update. Ps. I place my heater near the filter inlet for better heat distribution and less chance of hot spots with constant flow. Maybe this helps!
