Ah yes, I had a set of these from eBay a while back on my old 8130. I ruined pretty much all the pieces except the screen cover and battery door cover, due to improperly applying them. It was also hard to properly apply the screen cover without air bubbles.

If there is a trick to applying these, I may buy another set because I do like these skins. Simple, thin, also protects screen...and pretty durable for what it is. The $24.95 price is a little steep, though.
