I got to say i love this case, has a soft silicone inner with a hard rigid mesh outer. It not only offers great protection but it also makes my Nokia look very stylish and the screen protector and cloth are an added bonus. Would have paid double for this :-)
Although I am not sure if this cover would actually stop the screen from smashing if dropped, I am sure it would defo protect it. Its a strong rubber cover thats fits great around your phones shell. Some people are saying it doesnt fit very well but I think thats because you dont have it don correct, as mine fits snug and perfect on my Lumia 625
The combination of the plastic and rubber will certainly hold and protect your phone, but the black plastic seems to break suprisingly easily, and there's no glue keeping the black case attached, so it sometimes simply comes off if you keep your phone in your bag.
I'm not entirely sure this is worth the price. Depending on what you want from your case, you're probably better off buying a differently designed case.
