The review mentions its just the type of device to use to watch dvd's on long train journeys. The battery charge and the batteries themselves don't last very long - mine packed up after 7 months and they are only covered for 6 months by the warranty so you'll have to fork out £200 - £300 for a new one about once a year!!!!
My Advice - DON'T EVER BUY TINY (Go for a decent brand!!!!)

That's surprisingly quick. Which type of batteries were supplied - Li-Ion or NiMH?
