I've just received w w w.ebay.co. uk/itm/280843795367?ssPageName=STRK:MEWNX:IT&_trksid=p398 4.m1439.l2649#ht_4513wt_1163 purchased 3/4 so two weeks ago. I chose black and purple.
Unfortunatly i had to return my XpS due to the infamous yellow display tint and get it fixed/replaced so i havent been able to try the cases on.
First impressions though are great. The cases look and feel more expensive than 1.7£. The cut outs are smooth and seems to be in the right places. The texture and feel of it are somewhat similar to the phone it self.
Anyway i think these cases will do temporarily untill i get myself a red Nillkin case.
As soon as i get my phone back i'll try them on and post a picture!
