I ordered this case & screen protector, and have been using them for a week or so now.
The case is fine. I don't normally use cases, so my opinion may be limited here. Either way, it goes on and comes off without issue, and fits snugly when in use.
This is the third screen protector I've used on this phone. The first was a Zagg InvisibleShield, which had a slight negative effect on image quality, but a significant texture, which is familiar to all Zagg products, like a somewhat sticky basketball texture. I kept it on my phone for several months before it got too annoying.
The next one I used was a RealLook. This one was Beautiful. Like, just from looking at the phone, you couldn't see that it was applied--for a while anyway. The RealLook picked up scratches more easily than Anything I've used, I left it on for maybe 2 months before it became so scratched that it wasn't worth using.
This screen protector is a mess of compromises. It looks UGLY. Like, it makes the beautiful IPS screen look like some awful grainy samsung AMOLED. However, it Feels wonderful. Like, it has a smooth matte finish that makes up for the decrease in screen quality. However, with the cutouts for the cap keys, it makes the phone's front look busy and significantly less streamlines, Especially when using soft keys.
For the price though (~$9 shipped for both), they're Great.
