Hagen Thermometers Mountable Style: Glass Floating w/Suction Cup
Great features, sturdy.
These thermometers are very accurate in a 20H and a 5 gal aquarium. I dropped one on wood floor, survived with no problem!

temperture is very accurate
I prefer the glass thermometer over strips or digital thermometer.

Not a lot to say. It does what it should and is quite accurate. I use it in my sump. Would not recommend for a display tank as it could possibly knock into things but where I have it is quite good.

what do you expect?
It's a thermometer. Nice, small, accurate within reason. Its not digital so you can't get an exact measurement but then again, it's really cheap. It will get you within a degree and honestly that's good enough. I keep it on the side of the tank on the opposite side from my heater. If you keep your powerhead near the heater, that should eliminate a hot zone and circulate the headed water better.
