Query: No more neck pain :)

Well, my office decided to get these just for the heck of it even though no one thought we would need it. What can I say, it works well. It shipped very quickly to our office and the install was simple. All you do is just peel a sticker and attach it to your phone. You actually stop having to crunch your neck against your shoulder which is nice. Although it is bulky I find myself still holding the phone once in awhile. I don't think I'm used to it yet but I can tell that when I'm typing and talking I don't shrug my shoulders like I used to.
