Does anyone have experience with one of these main-furling systems?

I'm considering putting one on my current boat, if I choose to keep her for
a while longer. But I'm open to other suggestions. I'm not a fan of
in-mast furlers. Too risky, considering a jam with the sail half-furled
could be disastrous to the sail--or boat-- if caught in a blow. And mast
furlers don't allow for horizontal battens--I'm not sold on the new vertical
battens yet.

Any suggestions will be welcome.
