COD a set of nexus 4 bumper today! as usual on time and here's my review after having the bumper for a day.

1) feels like you're carrying just the phone without anything
2) quality is awesome
3) it's not very tight and it's not very loose i can say just nice? it feels just fine for daily use.
4) if you use a little force to like try pull the bumper from the side it will open up. not sure it will be loose after a few pulls like ( dont itchy hand la)
5) all buttons fully accessible without any prob
6) conclusion! quality: 90% functionality 90%
