is it the new revision or not?

if it is still same as original version, i'd advise against buying it.

i tested my friend's around a year ago and for me, the mouse is small and hard to use it properly, and yes, my hands are quite small. and it is hard to hold the left part with just one hand.

i suggest you to test-drive first from any game shop / friends before buying. who knows if it is suitable for you.
but for me, i wont get it.
