I bought this case, not hoping for much as it is so cheap, but after having a few other cheap cases for my 3GS from Amazon, I thought it would be ok. Upon opening the package, the case is a nice shiny white, not unlike the colour of my iphone, which is nice, but the case is chunky. I didn't think anything of the size until I went to put my iphone in my logitech stereo dock. It wouldn't fit while in the case, even though all the other cases I have bought have done (incipio feather plus others). This was an annoyance as I have to take the phone out of its case every single night to charge it. Due to having to take it out of its case, the case has worn quite badly quite quickly (couple of weeks) and bits have snapped off.
I look after my phone religiously and it doesn't have a single mark on it, so I know I am not abusing this case.
To be honest, for a cheap and cheerful case it is fine, and in all honesty, what more could you expect for a few pounds, but I won't be buying another one.
While the incipio feather cases are more expensive, and still split like the cheaper ones, they at least last a bit longer, and can fit in a stereo dock.
