This is a nice phone case which I bought for my daughter's w810i, having been very impressed with the one I have for my K750i. The material is matt black and rubbery in texture with a removable belt clip and cool logos on the sides. All the holes for the phone buttons are exactly in the right place so you won't need to take it out too often, though it is easier to text with the case off. Not sure why it's called a SCUBA case though as it's definitely not fully waterproof!
Overall, it is a practical, durable and attractive item, well worth the few pounds to protect your phone. Check the postage of non-amazon sellers before buying though, as it may work out cheaper on the High st.
