Only had my One X a couple of days and didn't like holding it that much as it was too slippery, I am used to having cases for the phones to stop the odd knock but didn't realise how used to having a non-slip surface I had become.
This case is great, it fits perfectly (even round the raised camera lens), has holes/cut outs in exactly the right places, is very thin, protects the and the non-slip surface now makes my phone a joy to use.
I purchased this as a temporary case while I made up my mind as to what permanent case I would get for my phone. I don't think I will be changing it for a while yet. I am surprisingly impressed and would have thought, if seeing this case on a friends phone, it would have cost a lot more than it does.
