Default Kensington K39591WW

I've got the possibility to get that cover at a decent price only today but I struggle to determine if it will be compatible with the N10 : http://www.kensington.com/kensington...and-black.aspx

It's supposed to be universal but from the comments I've read, it's not always the case (ah !). I don't find a consensus on the exact size, sometimes it is said to be too small, sometimes too big.

Does anyone have it ?
