anyone use: Roland D2 Groovebox?

hi, just spotted this from a few Youtube videos, seems to be an interesting perfomance/hands on production tool.
anyone had much experience with them? how easy they are to sync? and also it doesn't make it clear on the blurbs wether you can use more than 8 steps in a sequence, anyone know about this? i make extremely shuffled music and need those extra micro beats!
thanks
