Accurate but one didn’t last
I bought two of these to heat a 225 in a cool room. They were easy to set, held their temp rock-steady. I like the pilot light, red for heating and green for standby. One of them, 10 months old, developed condensation inside, which is a sign of a broken seal. So I’m replacing it with another one.

Difficult to manage temp control
I purchased a pair of these for my new 220g aquarium. I have one placed at each end of the tank. I've had these operational for a week now, and I'm still trying to dial in a consistant temperature. The video that accompanies this item is not valid because the model and it's controls have changed. There is a single red dial and the VERY SMALL temp number indicator is a range of four degrees (82 to 86) Not great for accurate temp setting. One would assume that if the dial was set close to 86 the temperature would be 85 (for Discus). I've set up both heaters for the same temperature, but after a week I'm still having to dial in the correct temperature. Today it's sitting at 83.7 degrees. For the price of these supposedly high-end heaters, I would have expected more accurate control settings, and more accurate temperature control. Very frustrating.

Temperature is off by 4 degrees or just not heating
I don't know if these new eheim are just not made with the same quality anymore. Just sent one back because it wouldn't even turn on right out of the box. Order 2 new ones. Temperature is so off. Set both heaters to 86 F. Just be at 82F where I want to be. Heater would go to 82F and then drop to 78 the next day. I Unplug ans replug.. the power cords. Temp goes back up to 82 but than again..... right back 78 the next day. The are both set at 86f. Wtf is this.

Very nice
Bought on recommendations from several aquarium forums and I'm not disappointed. A very stout heater that works well. My only (minor) quibble is the temp control isn't well marked and the heater has to be pulled from the tank to adjust (takes 2 hands) and the entire unit cannot be submerged (there is a water mark that must be met at the top). Other than that, a solid unit.

Condensation in heater
This heater is only 4 months old and already has condensation build up. You can also find this exact heater for $70 at most local fish stores.
