i know of two people who say they are allright, i have one myself that i was given sat that i use as a paperweight in my workshop because i dont dare bolt it onto my cossie because just to look at it appears cheap and nasty. the bolt holes for the exhaust housing dont even line up with exhaust flange and the gaps around where the compressor housing fits on are not even equal all the way round!
things are cheap for a reason imo!
