That's what my buddy has used on his Note 2 and now Note 3. So far so good with his. At the very least it makes the phone so grippy you're less likely to drop itShit, did NOT know that about them.
and noted about the Spigen cases. I just have a basic bodyglove case on mine and been good(or lucky).
This one fell exactly two feet - from my bed cover down to my tailgate. Landed on the bottom right corner and the screen broke about 2/3 up on the left edge and cracked from there. So the phone itself received enough shock to flex and break the screen - a case that can't isolate the phone from that amount of stress in a two foot drop isn't worth having on. Without a case it probably would have still broken, but that's shitty testimony. "Our cases are about as good as not using one at all - check out the pretty colors!"
