I bought a new Nexus 5 and was looking for a case to protect the phone. I tend to let phones slip my hands (big hands, slippery fingers). With this case I have not yet let my phone slip to the floor and I know I can put it on my table and not get it scratched. A little bit on the bulky side but not that much and I honestly don't like phone that are too slim anyway. If you want true protection then this would be a good case. Not a super fit if you use the cardboard printouts they sent but I forgot to put those and don't want them.
Just close to the power supply socket there's a small gap that let's some dust inside of the case trapping it in between the case and the back of the phone. Still, not a big deal. I would buy it again specially for under £7,00 as I did.
