Spigen Glas.t , Spigen Glas.tr or Bodyguardz Pure?

[Oxydiom]

Hey people
I've searched a lot about a perfect glass screen protector. I need some review from people who own these products: Spigen glas.t, Spigen glas.tr and Bodyguardz Pure

There are a few points that I have seen after searching a lot about them:
1. Spigen glas.t tends to chip at it's sides. My question is that does it chip even if it's in a case? Spigen has a new deal which gives a case and a glas.t for 35$

2. Does spigen glas.tr chip too?

3. Is pure any better than spigen products?


Thanks I'm gonna order one of these tonight
