Not everyone has two completely functional hands, but they still enjoy woodworking safely.
There's another thread going on here about vibration induced pain from tools, and some of the responders mentioned their carpal tunnel syndrome.
I can see it being used by them to get something placed, then following up with standard clamps when there is less to hold still.
I'd like to see if it goes down straight and holds firmly enough to allow someone to do that.
The advertised battery life does seem poor, though, and it appears that it could sell for $10 less.
My 2 cents.
