I have a Tunze osmolator, I am happy with it, there are a few issues to be aware of though.

One is the electronics are a little delicate, I fried one osmolator doing something innocent a few years ago - plugged in another item into the powerbar which made a spark and blew the circuit, everything else on that circuit was fine but the osmolator was shot.

A couple of times my unit has stopped working because the optical sensor head got covered with precipitated salt/calcium buildup. You are supposed to clean the optical sensor with vinegar every few months, make sure and do this before going away on vacation.

Overall it is a good unit, keep the level very well, worked well with a kalk reactor in series when I used to use a kalk reactor.

If you can handle a little fluctuation in your water level (up to an inch) I've been using the Tsunami AT1 for 7 years never had a problem. Actually never even clean it.
The SpectraPure version says it only varies the level 1/4".
They get pretty good reviews on R/C.
Tsunami AT-1 and SpectraPure controller both use air pressure to activate and deactivate an outlet.
Just don't trust the suction cups, I made a mount from a MJ bracket.
