I like mine a lot alright it didn't exceed my expectations. The only problem I've had is that the thermostat on the heater says 80 when the tanks 78. Alright i did but a oversized heater at 100Watt to a 10 gallon.
no complaints..... i have a 50watt paired up with another heater in my sump ....i got it as a X-mas gift and it has been running solid ever since....i am going to be purchasing another very soon....if i had to complain it would be that they are a bit pricey
I've had two in two different tanks for over two years. No problems at all, although I agree with brandon4432 that the thermostats are off just a hair. I would absolutely purchase another.
