I JUST installed bodyguards pure. I'm currently weighting it down just to give the adhesive a chance to set but I did pop my phone into my defender case and it snapped together with no undue pressure ....
Update: Yeah, this is the perfect combo. I may need to tweak the home button a bit. I added one of the buttons included with the bodyguardz pure but may need to raise it a bit higher
I never had much of an issue with the defender's bulk. My iphone 4 spent its life in a defender. I didn't even mind the screen protector as it had a nice glide to it after it picked up a good coat of smearThe problem I had was I could detect and obsess over the tiniest bit of dust so I was constantly cleaning it and re-cleaning it. The Pure solves all that & I was fortunate to get a dust free installation.
Can you please keep us updated as to whether the defender makes any marks or scratches on the glass screen protector?
