I bought 3 packs of protectors and followed the online instructions (there were no paper instructions in the box). I've installed dozens of them over the years, but I still follow the suggested directions. Installation is done with the "Hinging Method” basic sticker, it is elementary but simple. The leaves are borderless, the right size and don't bother the camera at all. So I tried to install the first sheet and didn't fully adhere to the quarter sized portion of the top edge. It wasn't actually an air bubble, just not glued (the screen was completely cleaned with the trusty wet wipe). No matter how many tries, the same area won't stick. The second sheet was fine except for an eraser-sized mark that didn't stick to the corner. Again, no matter how hard they tried, and only that stain wouldn't stick. Honestly, it was probably good enough, but I didn't pay for "good enough," I paid to be right. I didn't bother with the third leaf. I returned it. If I buy 3 sheets I can use them on 3 devices instead of 3 attempts to find a broken free sheet. I bought another slightly more expensive brand that worked with no problems. Sorry I think it's just not the best product!
