I bought two of these (another colour as well as this one). Great product that has the feel of a scuba wetsuit. Actual dimensions of case are: 21.2cm x 15cm x 2cm. The side pouch height is exactly 10cm. Now I have put in my Presigio Multipad Tablet PC (Model # PMP3270B). The dimensions of this tablet are exactly 19.7cm x 11.2cm x 1cm. This case fits this tablet perfectly. Snugly with no room to spare on the length but you could possibly go another .5cm on the height. If you go for anything bigger than this tablet's dimensions, it will not fit this case. I hope this information is useful.
As far as the quality of the case goes, it is pretty good and I am very happy with the zips which runs very smoothly and do not snag at all. The wetsuit material is also very nice and will definitely protect the tablet from bangs, knocks or drops.
