CJ,
you are able to slip the case onto the back of your PDA? I think that I may have a defective one then, :rolling: cause for the life of me, this thing will not slip onto the back. I mean I can physically force it, but it pops off at the slightest provocation, and it is not flush with the back. The tabs bend out and look as it they're going to break off. The bending causes the cover itself to flex, hence it does not sit flush. Are you able to smoothly slide it onto the back side of your 51v? If so, I have to give bull gaurd a call. Also, has the cover scratched the black portion above your D-pad? Thanks in advance for any information.
