After going through 2 sets of these I have thrown them in the garbage. We used all 4 lenses and could not make out what was on them. I can find nothing sharp when looking at my screen. Total waste of money. Bought another brand this weekend to replace these. This is a piece of junk that would be OK if they were 5 bucks. Not recommended. One star for Amazon Prime. As long as you get free shipping, go ahead & try it out. No hassle.

Bad review

Ex Input:
Good quality product. Fits nicely on the iPhone 4s. The screen protector has this weird rainbow effect. But other than that it does what it's supposed to. I would buy a similar product from Tech Armor.

Ex Output:
Good Review

Ex Input:
Well, I received it in a timely fashion and that's where the good news ends. To be specific, if you're looking for something to fit over your ear- this should not do it. The head band is too low up on me. It didn't even cover my ears. I had to get another one. Maybe mine was defective.
