i have i prizm thats been running for about 6 yrs or so.its a bit loud and i replaced the air hose last year.thats all that ever broke,actually the hose shrunk.i had to adjust it alot until i started running a sump,now i only adjust it once a month or so and it works great.also i put a valve on the air hose neer the collection cup for easy turn off while emptying the cup.
