The case is a nice TPU material that offers a slightly better texture and grip than the plastic back of the S4

Great So far good battery life a little heavy but gives the phone a more solid feel and grip

It's big and bulky, but nice hard rubber case---allows for good grip of the phone.

It does exactly what it's supposed to do!The case itself has a really nice grip around the phone, it's a perfect fit

It gives a good rubber grip to the phone and just peels off for easy removal/installation but not too easy like silicone.

The grip is important as the weight makes the phone easier to drop

but i love it better grip and almost lasts 6 days with moderate use

The edges are also square instead of being rounded (think: brick), so I find that it's hard to find a comfortable grip

The case is a great material with excellent grip and shock absorption

It will take a bit of getting used to the difference in weight however that only took me a couple days to do.it is very much worth it for the absolutely incredible battery life.also as I mentioned the small amount of extra weight actually makes the device feel more sturdy and gives me a better grip in my hands

I actually like the extra size because I feel like I can get a better grip on the phone

and I love that it is a little thicker allowing for a more secure grip.

Provides some cover for the camera as it is now situated a it deeper in the phone5) better grip than the original S4: significantly thicker, less smooth (but clean matte black)6) great fit around the edge of the screen: can easily be taken off but does not that easily so it shifts on the phone while in normal use7

The rubber they use is very cheap and lacks grip.

Creates a strong grip on your phone and belt

It provides a good grip, definitely not a print magnet, i really liked it

It renders 3G/4G service unusable with a weak or marginal signal.

The 4G works fine with my Samsung 4s!

No issues with the reception (2G/3G networks)
