I'm chuffed to bits with this case, which arrived a day earlier than advised.
I've had my Moto G 4G LTE for about 2 weeks now.
I'd already ordered a screen protector and a couple of cheap "trial," cases from Amazon in order to make sure that, as soon as I'd purchased it, that it had protection out of the box.
I was tempted, given that, the Motos have interchangeable backs to leave the back "naked," as I love the feel of the Moto in my hand and the "dimple," is very useful when holding the phone with one hand.
However, I decided that, even if I could change the back, there was no real protection for the sides and the power/volume buttons.
The 2 cases I'd ordered were OK, one was a clip on shell, but, like most of these left the top and bottom without any real protection, the other was a standard "S Line," TPU case, which was brilliant, other than the fact that it kept accidentally triggering the question as to whether I wanted to "shut down," the phone when I moved it, picked it up, or turned it to Landscape mode, which became a bit irritating....obviously it was gripping the power button too tightly.
For me, this case is the best of both worlds.
It combines the protection of a TPU case with the rubber bumper, which, when on doesn't feel that "rubbery," to me and which provides some good "grip," on the side, a real feature of the "S-Line," cases and the sleekness of the original Moto G shell on the back.
It wasn't as difficult to install as some efforts I've seen on You-tube, or read about in reviews.
I'm not sure how easy it'd be to damage the actual back, of the case and, as others have said, it's not very "grippy," on the back, but these are minor details for me, as it's replaceable and a lot cheaper on Amazon than on the official Motorola Website.
I've gone for the plain black one, in order to keep the look of the phone, as I bought it, originally.
I'll probably order a 2nd case, in order to have one at the ready, should this one ever get damaged!
In short, it looks and feels great and I'd thoroughly recommend it to anyone who wants to keep the feel and look of the Moto as it come out of the case, but who wants the security of knowing that there's some added protection there..
Oh and Gorilla glass, or no Gorilla glass, having seen a few smashed screens of late, I'd always recommend a decent Screen Protector and, if, like me, you can't fit the damn things and they're left with dust marks/bubbling, take it along to the Carphone Warehouse and they'll fit it in 5 minutes, for a fiver! :O))
UPDATE: 6 WEEKS IN!
I have to say, that, having used this for 6 weeks, or so, it does tend to pick up fingerprints and marks very easily.
I sort of wish that Motorola would use the same material for this, as they do for their Flip Shells.
That said, and having tried a few alternatives, I've come back to it, over and again, as I still think it's the best case out there!
