I have a one pice 5 arrow quiver and LIKE it!

No problems with it falling off???

I really have to PRY on mine to even get it off? Maybe he got one with bad rubber or wasn't using it properely??

I would have called Alpine about it...I am sure they would back up their product.

Cannot comment on the 2-piece but if it is as good as the 1-piece you will be happy with it...
