Mine was delivered on Saturday!! (I was away from home all weekend - just got it and put it on last night!)
I love it. I don't think it adds too much bulk... With the case, it is about as thick as a naked iPhone 4.
The shine doesn't really have any grip to it (not sure about the regular DualPro), but it feels less slick than the naked phone. I think the little extra bulk helped make it a little easier for me to hold.
I also feel more comfortable if I were to accidentally drop it. Seems like the case is pretty sturdy.
I still would like to find a decent thin tempered glass screen protector to use with it. But so far, I'm really happy with it.
As far as finger prints on the back go, if you touch it with greasy fingers, it will leave a finger print... but it wipes right off. I don't have a problem with this. It isn't any different than the back of the naked phone in that regard.
