pataykangbataka I do not know how this guy has good feedback but somehow he does. I bought a used eshopps psk-75 from this guy it looked fairly clean and he had good feedback. It arrived and looked good but after I finally got my tank running I set it up and boom the pump wouldn't work I gave it a good freshwater bath and cleaned it up some and it started working about an hour later I walked by the tank and it was not working and seized up now it will not work. I contacted this guy and he immediately tried to say I switched the pumps and am trying to return a different item. He is a piece of work and acts very childish I recommend to stay away form this underhanded piece of work.
