If you're looking for an ultra durable protector for your iPhone 5 that'll keep your screen looking nice and shiny, look elsewhere. If, on the other hand, you want a cheap, but effective protector, that'll eventually require replacing, this will do the job.
This is actually my second screen protector - I got one with a case that I bought, but owing to how terrible I am at getting these things on without bubbles underneath, I bought some spares!
In comparison to the other protector, these feel flimsier, and not as high quality, but there are 6 of them, so for the price, I'm not too fussed. I was able to get these on first time, and with no dust or bubbles underneath, which is practically unheard of with me. Unfortunately, the low quality of them means that fingerprints and smudges show up on them much more apparently than the other protector, and the smallest of scratches look like dents. I suspect a few more weeks of normal wear and tear will result in me having to replace the protector with one of the five remaining ones in the pack. However, so long as its only the screen protector that I'm messing up, and not the screen itself, then it is doing its job!
