Stevie:
I've had it a few weeks now and find it great. The one I bought was advertised as ex-demo or in a damaged box. It didn't appear to be either to me. It was in perfect condition and I'm sure the box had never been opened.
It's a cool piece of kit for the money and has a huge working area. The mouse is crap tho but I have a decent wireless mouse and only use it for zooming in and out when PPing. Everything else I use the tablet for.
As for the batteries, the tablet does not require one, it's USB driven. The pen needs 1 AAA battery and it is expected to last a year with normal use befor needing replaced.
I highly recommend it.



Hope this is of help
