I have had great success with eGrips. Absolutely no peeling, wearing out, or difficulty placing my BlackBerrys in their cases.
Here are _three tips_ to prevent the peeling problem that some report here.
1) When you purchase eGrips they come with an alcohol wipe for cleaning the surface of fingerprints, or any other residue. So use the wipe first.
2) Apply the eGrip to the surface and once you've done that. Then put the palm of you hand on it as press it down firmly and wait with your hand in place for about 3 or 4 minutes. I have found that this "warms" the adhesive backing and the bond becomes very strong.
3) At this point, it's important to Not put it in your case for just one day. eGrips tend to "cure" after 24 hours and then they stay in place and do not peel.
I use eGrips on the battery door, along with an OEM BlackBerry leather case, and find the eGrips present no problem with inserting the BB into it's case.
I have this combination on both my 7130c and 8700c and it's worked perfectly, and has been very long lasting.
Cheers....
