There is a very good reason why this is so cheap whilst claiming all this funcionality. After unboxing, charging through provided mains based/removable USB cable and hooking up to my computer through USB, everything was fine on the first 2 tries, after that explorer hangs (windows 7) after picking up removable drive, so you get the windows endless thinking icon on an open explorer tab until you either end task explorer or reboot, niether option being good. That in mind, bought the 32gig micro sd card to bypass linking it directly to computer to transfer files. Worked a treat for almost exactly a week, then got screen corruption in the form of a load of dead pixels center screen. The fact is, you get what you pay for, and this device really is too good to be true, for the price. Buy a dedicated mp3 player without a 4'3inch touchscreen (touchscreen on this is unusable without either fingernails or stylus) or indeed video playback, (not from apple, I-pods, like all apple stuff, are laughably overpriced). I accept the fact that I may have been unlucky with this product, when it worked it was a thing of beauty, but reliability is more important no? Ask yourself if its worth all the hassle of having to send it back? Im going to keep it as an mp3 player backup, but I wouldnt buy it again(mp3 top volume is pretty low), and I'l be twice as wary of these type of imports as regards electronic devices. No offence, but once bitten, twice shy.
Also to clear up some issues other reviewers have had, it is lockable if you switch it up briefly in the same direction you switch it on (5 sec switch-on time is a bit long, by the way). Its a potentialy good product, in other words, but massively flawed by trying to do too much. Or maybe I just got a duff one...Who knows?
