For 2.50 this is a steal. The case fits my nexus 4 perfectly and makes me much less fearful about the consequences of it smashing. Unfortunately it covers up the lovely back meaning I can't look at it, but on the other hand, it covers the lovely back so I can't smash it by accident!
I haven't fitted the screen protector yet but I think it lacks cutouts for the light and proxmity sensor, which I expect will cause problems (likely the phone won't know when to switch the screen on, assuming I'm holding to my head) but I'm going to use a hole punch to knock a couple of holes in it (to match the film fitted to the phone as new) which will get around this.
All told, though it's certainly not a premium product, for the money this is great. Ordered a clear one too - cheap enough that I can do that and see which looks better :)
