Ditto, I dropped one before I even used it and broke the top so it was unusable. Went to a local retailer and got another one as I was going to hunt the next day. Got home and opened the package and it was cracked already.
Took the one that was totally wasted apart and will take it to the hardware store to find a suitable thin wall PVC and re-engineer the critter.
Will post photos etc if it works out.
