Supposedly pretty good, I've got an otterbox defender and will happily throw my phone without a worry in the world. Good protection is always worth it.
I had an otterbox , was using it in an environment where there was brick dust and now I have a nice triangular shape around the earpiece of my iphone screen. I emailed the manufacturer and there response was pretty much "thanks for your feedback"
It is definitely recommended! It costs around 15-20 depending on the model and has a lifetime guarantee! You can't notice it on the screen, it never bubbles and means you never get scratches either. Because youdont notice it it's like having a normal screen that will never damage. You can get a back one too if you don't fancy getting a case due to it getting bulky
I've had one travelling for last few months and my phone looks brand new still and not even a hint of it peeling back or bubbling! They do it in a dry vacuum for hour and a half so it's pretty much stuck on for good
It's a screen protector for iPhones/smart phones/tablets etc that is done under a vacuum so it should never bubble and look like you have a plain phone just without ever getting scratches

What is it
I think it's like a cricket box but for your phone.
Trouble is most cases make the device bulkier if they protect well , this is more about preventing scratches .
