I have this and two other PocketLabWorks products.
All three work great, and support has been even better when I had some issues starting out.
While I can appreciate what another reviewer said about the cable cost, I did some exploring of other options before buying. The iRiffPort cable had the best reputation/reviews and worked with the biggest variety of apps by other app makers.
Its kind of like the iPad itself… not the cheapest tablet out there, but the one that works the best so you can actually spend your time using it, not fighting to get it to do what you want to do.
Thats just my experience/opinion, though.
