i had a proclear for a year before I had to get rid of it bc couldnt fit the overflow on my new tank without a lot of handy work and "ruining" my new tank.
nothing but good things to say about the proclear. it was even one of their first models, so it had been used for at least 4 years before i even bought it. could feel the quality
my buddy has a del rey 125 going on a year now. bought it used as well. no problems with that one either.
(CPR overflows were used with both these sumps, no problems with those either)
