Ive been using this for a few months now. Its a lot better than the cheap one I had before. If you have a k800i and you want to protect it from scratches and knocks and bashes that occur from regular use, then you have to buy this. Its really cheap and will protect the screen from becoming scratched. It seems durable (as my other one had broken at this point) and it is relatively easy to put on and take off.
The only thing preventing me from giving it a perfect five is the small crack thats appeared on the back where the slider and speaker are (probably because its the thinest part of the case and usually has the most pressure applied to it).

fits great to the phone and does a good job but mine broke within the first two weeks and has resulted in little bits of sellotape to hold it together

order mine on saturday got it on friday I was not in any rush to get it good for its price if it breaks i get the proper case I got it just to try.

these cases are cheap and cheerful, mine lasted about 6 month, before the clips snapped on the sides. but for 2.99 who is complaining? as least my phone is still in good nick

The problem with most mobile covers is that they make your phone look and feel much bigger than they are, and we're not in the 80's anymore so we don't particularly want to carry a brick around. Having just got myself a new K800i I wanted something to protect it a little, especially the excellent screen and the lens cover for the camera which is far too exposed. Seeing this on Play I thought 'what a good idea' so I bought one. When I received it I thought it looked and felt a bit cheap and had some rough/sharp edges. All the holes are in the correct place for the K800i's buttons (it has a lot too!) so no problem there but the part that covers the screen makes it look a bit blurry but still useable. The main problem I had were the fasteners either side of the phone (where the case clips together). As it pushes the case out a little when the phone is inside it puts pressure around the fastener and in my case that caused it to crack and made the fastener useless (the case kept falling off after that). Of course this could just be the one that I received and others may be fine, but I'm not going to buy another one to find out! All in all I think it's a good idea just a little poorly done and worth 2.5 stars (but you can't do half stars so I was generous and gave it 3).

this case is a good idea and yes does look strong. but the thinner bits on the eages have broken, I am so carefull with my phone and dont know why this has happene, i guess its a fault in the design. good idea shame it does not last.
