i'll chime in and say honestly my RODE blimp sucks. I read alot of reveiws and luved Matt's own especially...however i ordered mine from dvestore and when it came it was busted crap. Meaning it was missing a bolt, the lever that adjusts the slide thingy snapped like it was brittle...the xlr jack would not stay in the handle so during shots it would slip out and hit againts the boompole. the bolt thing that u screw the boompole into would not stay in...Just crap. So i had to to get it replaced (not an cheap thing when u live where i do) and the new one still has that xlr problem.
But did the replacement function better? Sounds like you got an anomalous dud the first time. I have a RODE blimp and it holds up very, very well. The XLR cable doesn't work itself out easily, either. You might try wrapping some plumber's tape around it to tuck it back in. It needs to be able to come out for repairs, but you should be able to get it to stick in there.
