Yep, that's the one! It is a bit long, but it's also not fully submersible (although I have heard reports that it secretly is... but the directions say it is not), so you have to mount it vertically and be sure to have the top out of the water. I absolutely love it. The mirrored tube blends right in in my aquarium, and the pilot light is blue, which is a nice change from red and orange on all the other heaters hahaha. Anyway, it keeps my tank's temp rock-steady at 80 degrees and I've never had a single issue with it.
