I've had the 200 Watt (Dual Element) Helio PTC Smart Heater for about a month now on a 20 gallon IM AIO and I have to say, I'm kind of impressed. Both of the elements have LEDs in the cord end so you can see when each is actually on which helped when they were deep down in the bottom of the filtration area. The controller display is simple and easy to use and comes with sticky velcro strips for mounting, and hold well. It has a cheesy retro 3D effect, but in a good way. The temperature probe also looks like it is titanium which is kind of a nice touch. I've had it set to 78 the entire time and I just now pulled out the NIST validated temp probe and it read exactly 78 in several spots in the tank. I hope the longevity lives up to the hype and I would definitely recommend these heaters.
The only thing I would change is the low temp alarm when setting up the tank. I wish they would add some logic that if the controller was just powered on, don't alarm for low temp unless a certain amount of time goes by without the heat rising a certain amount.
