I ordered the PDair slip case (without clip, LINK HERE) about a month ago after seeing quite a few good reviews, and knowing I wanted a good leather slip case. It took about 3 weeks to a month to get to me unfortunately, which I was not pleased with, but when I got it, I could tell it was good quality. However, the case does not exactly seem to be made for a droid. It is an incredibly tight fit for the phone (my phone has no screen protectors or anything). It is the correct height, but it is VERY hard to get the phone out of the case. It usually takes me about 10 seconds or pulling and tugging while trying not to break or scratch the sides of the phone.
Also, because it's being so rudely tugged out of the tight case, the battery plate almost always gets pulled off and flies to the ground. It really isn't acceptable.
I've tried stuffing the case with materials to stretch it, it's sat for quite a few days being stretch to its max, but still is just way too tight. The problem with stretching is that the case's sides are elastic, not leather, so they don't really maintain the stretch.
