I have been using one since it came out. The touch scroll strip is very spotty, not sure how much of that is software, but fine product otherwise.

If you open it up, the strip is actually a thin PCB glued to the underside of the top of the case. Mine was a little loose, pressing it down made things work a bit better. It does still get worse at tracking when the batteries start running down (a sign that they need replaced/charged!).

Even when it’s working well, its resolution is disappointingly low though. More like a mouse with a scroll wheel with fairly large detents than the trackpad-like scrolling I was expecting.
