I got these from ebay:

It some kind of glue-less material. For the price (for 4 screens) and ease of installation I think its worth a try. However some negatives
- probably less than 1mm off the bezel on the horizontal
- some of the edge on the vertical doesn't seem to stick to screen. Not noticed any stuff getting underneath or lifting (yet). Not sure if thats the case for ALL screen pieces out of the 4
- instead of 2 holes for camera,prox its a round cutout so that area is un-protected.

The screen itself is awesome, very clear no bubbles whatsoever, no loss in senstivity. If not for the edges and the cutout, it would be impossible to notice its there. Infact it feels better as I'm not afraid to use nails now

You can get the same thing cheaper from other sellers outside USA
