I had one of these...Frankly I thought it was crap.Didn't seem to suit my GO 7 port at all...build quality wasn't all that great either..pipe discolored really quickly and it didn't take much of a tap on the stinger to crease in the side of the pipe..I ended up giving it away for free..Spend a few $$'s more and get a 2047 or a 2072 or an 0801..
