Hydor THEO Submersible Aquarium Heater 50W UL ( Nov 21, 2010
By chelma
It is a good heater. I think the temp might be a little off. i have it at the highest setting and the thermometer says 77 degrees, but it is in a very cool room

Works well so far... Nov 21, 2010
By BipRoberts
Just bought the 50W model for my 10G tank. I set it to 79 degrees, and the thermometer agrees to this *exactly*, even on the weak side of the tank away from the filter.
I know that I haven't had it long, but so far, so good.
UPDATE: 2 months in, it still heats well. The ambient temperature in the room has an effect on it, but the temp is staying +/- 2 degrees from 80. For a $20 heater, I'm satisfied with that.

 Nice compact size, accurate, stable Jan 03, 2012
By Carolyn
I ordered this heater because the one I already had was a little too bulky for my 5gal tank. It has been running for several weeks now and the only problem I've had is it runs about 3 degrees F above the setting but it is very consistent with the temp. I like how small this heater is without sacrificing wattage, I like the dial on top that has actual degree settings, I also like that there is an on/off light. I would recommend this heater.

Been working great so far Dec 28, 2011
By J. Rader
I've been using this along with an Apex controller and my temp is always between 77.5 and 78. No complaints but I've only been using it for a couple of months.

 Runs HOT, and Leaked Feb 23, 2011
By Christine Roach
I've had this running in my 6 gallon tank for a week, but I'm returning it to amazon because it has been keeping my tank a full 8 degrees warmer than I have it set. I want the tank to be about 75 degrees, but I have to turn the heater almost all the way to its minimum (67) to keep it at that temperature. The good news is that it maintains a steady temperature. The bad news is that if I ever want the temperature to go cooler, it really isn't an option. I also worry that some day it's going to cook my fish. I could accept a degree or two of inaccuracy, but to be a full 8 degrees warm is a bit much for my taste.
I don't think this is happening because my tank is small - the heater should still turn off when the water reaches the proper temperature, no matter the tank size. I think I just got a broken heater. Hopefully the replacement will be more accurate.
*EDIT* I will be returning this heater to amazon, and I am waiting for my new heater to arrive. As I look closely at this one, it appears to have leaked - there is condensation on the INSIDE of the glass tube at the bottom. Hydor, I am not impressed. I hope it doesn't explode in my tank or anything in the next 24 hours, and I especially hope that the replacement is significantly better.
