Glad you like it. When I was working at the LFS
, the Mag pumps were very popular with the customers (and the boss). Everyone I know seems to like them and recommend them.
Rio's will last about 5 years tops (more like 3 realistically)with proper cleaning, mags will last double that with taking them out and running them in a bucket of vinegar water to get the buildup out once every 3 months or so.
I've read a lot of horror stories about Rio's... it seems that they not only fail OFTEN, but that the failures are catastrophic in a much higher incidence than other brands. By that, I mean that the impeller seizes and overheats to the point where the thing blows up and leaks stuff into your tank, or that it actually electrocutes you on occasion!
You should be really happy with the Mag- good luck!
