So I've had my Vox for almost three weeks now, at first I was fairly pleased with it and was OK too read off. However the touch screen was fairly unresponsive and froze a couple of times. The battery life was on average 2-4 hours, about two weeks in it froze and I reset only to find out all of books had been deleted so had to upload them all again :s. Also it is not ideal to read in only one hand and 90% of the time required both hands.
I took the vox back to the shop today and swapped it for a Kobo Touch, which is a lot lighter and easier to hold, hope this one turns out better than the vox, will keep you all posted.
