Rarely write reviews but some how I managed to get this case for 7.99 (off play.com as well). At the time of writing this review the price is at 35.19 pounds so you can imagine how smug I am feeling right now LOL.
The case itself is fantastic and totally protects my phone. The build quality is spot on as well. Although I definitely wouldn't pay over 30 for it! That is not to say it isn't worth that amount. Also after doing some research I would have to say this is probably one of, if not THE best case for the s2.
