I totally recommend the Phone Suit Elite. I have the white 4S and the Phone Suit Elite is really great. First of all it has plenty of power and does recharge your phone from totally depleted to 100% in around 2 hours. Really quick. My expectation was for the battery to work perfectly and it has. What I wasn't expecting was for it to be my favorite case as well. Not crazy about the extra weight (which was expected being a battery case) but I really like the case itself. The material is a matte white which matches the white 4S perfectly and when I say perfectly, I mean perfectly. Being matte it doesn't show fingerprints at all. It also hasn't scratched at all going in and out of my purse and all over in the weekend use. The front has a tight fit and the edges clip on the metal part of the phone thus not interfering with a screen protector. I totally wish that Phone Suit also made a non-battery case just like their battery case and I would be one happy camper. I primarily need the battery case on the weekends when I use my phone non-stop. During the week I would love an exact but slimmer version minus the battery case from Phone Suit. That's really how much I like this case. I have searched high and low and haven't found one yet. I do have a Case Crown Glider on order which should be close but has a shiny finish rather than the matte.
If anyone has come across such a case, please advise.
