I followed the threads when these were introduced for testing. At that time, they did not have any controllers for them, but said they were working on them. Sorta looks like they have them now. The good thing about them, is they are 2 seperate pieces attached by a magnet.
Scott, no holes are drilled thru the glass to make them work. Put one piece in the tank, the other on the outside and the magnet holds them together. The part with the motor is outside the tank so there are no wires in the water or heat from the motor. I have been debating getting a couple of these over the Tunze. Now that a controller is going to be offered, looks like I may get a couple. Melv in Dallas was one of the beta testers, I sent many PM's to him about them. They look like a good pump to have so far.
