ViaAqua 200-Watt Quartz Glass Su... vs Fluval E Electronic Heater

It looks nice and it heats my 29 gallon tank great. It hovers above the gravel line and the “water line” indicator and my tanks water line are exactly a perfect fit. It stays put, though the suction cups should be on longer stems.

It works ok, but there's a constant fluctuation in temperature of +-5 degrees. The thermostat in this thermometer is pretty useless. Looks like it has a built in thermometer, but it is just the temp setting.

Terrible product, very cheap. It suggests you cal an electrician if you do not have a gfi outlet.
