I bought another replacement plastic shell because it broke after about six months after purchasing. I drop my phone quite a bit and my phone is still in one piece.
Let's be honest, not every girl is meant to carry a purse. I am an avid fan of slimline wallets (business card holders) to keep the couple things I need with me. My "out the door" checklist goes Cell Phone, Wallet, Keys. This makes that so much better because cell phone & wallet are all one piece.
I've wanted to get a wallet case for a while but all of them had features I hated. To get more space you had to get a wallet that folds over. I see my friends having to unfold their phones and the flap always gets really beat up. The fabric pockets also stretch after a while so they drop cards regularly. The fold over wallet is also bulkier which drives me nuts. However if I went with the plastic hideaway case you could only get 1 or 2 cards to fit which just isn't enough for me. And the swing-out plastic doors have a tendency to break a lot.
I decided to test out the Otterbox case with my work phone because it had potential but cost a little more and I didn't want to pay for it just in case I didn't like it. It took me about 5 minutes to fall in love with it. It easily fits that third card that I needed space for (separate work ID card) and I can sometimes cheat and stick a folded bill in there too but I know that's not recommended. I don't think that the case has the RF blocking technology but I like it because I don't have to take my ID out to open the door at work. I just keep that card on the bottom and hold my phone up to the touch plate to get in. The case is just a bit thicker at one end - it kinda looks like a charging case but is actually a bit more low profile than the charger cases I've seen.
I am now on my 3rd case of this kind (keep changing work phones) and the only complaint I've had at all is that when I first get the case it's a little difficult to open. The last one was so stiff that I actually had to fight with it for about 20 minutes to get it to slide open. The trick at the beginning is to apply the most pressure at top of the slide in the center of the panel and just work it open and closed a bunch of times until it gets a little easier. Of all the problems to have, I will absolutely take that one. And the stiffness works right out after about a day of playing with it - BUT the case still clicks to lock so you don't have to worry that it's suddenly less secure.
