Brilliant case. Had mine a few weeks now and the blue back is still pristine despite working in a harsh environment. Overall size is 63.5mm x 119mm x 13.3mm. So makes the phone fair bit more bulky. It fits well. I have a screen protector on the front and back of my iPhone 4S and have no problems with getting the case on. The join line where the front/back parts of the case clip together are well matched and tightly together so no gaps.
The cut-outs for headphones, buttons and charger connector are well placed and give good clearance, the downside to that is it traps a lot of dust which can make its way inside the case so periodically remove and clean it out.
Nice rubber feel to the sides, well made and should last a good length of time.
For £5.99 Feb/March 2014, from PhoneDome it's definitely worth the money. They delivered within 3 days.
Overall a solid 9/10. I've had all sorts of cases and this is easily in the top 3.
The mirrored apple logo and raised iPhone lettering on the back is nicely done and looks very very good.
Would recommend this case to anyone looking for good protection for their iPhone and who also want something of good quality that will last them a long time.
