I've been using the PowerSkin no for about 2 weeks and thought I would post a small review. So far I like the extra power I get, a fully charged PowerSkin will keep the phone at 100% for 12+ hours with moderate use. I noticed that using Pandora will drain the case fairly quickly if it's not at 100%. It takes about 4 hours to charge a drained case to full charge. I like the feel of the silicone rubber, nice soft texture and it keeps the phone from sliding. I also like the extra weight it gives the phone, makes it feel a bit more substantial while also making the phone thicker, easier to hold on to. The only thing I don't like is the the fit, it's a little too loose. It fits ok, but I wish it fit a little more snugly, but that's just me. Overall, I think it's a good accessory. I had an Otterbox with the plastic screen cover which was a magnet for skin oil and once the plastic had a few prints on it, it would distort the image on the screen, almost like it was magnifying the pixels. Plus it added a little too much chromatic abberation to the distorted image. The distortion wasn't great, but enough to be annoying.
