During the last week, due to RSV, I've had plenty of screen time I've looked at several jigs / sleds that feature Match Fit Dovetail clamps. They seem almost too good to be true, but are rather spendy. It amazes me that for the length of time they have been around, there isn't a Chinese knock off available. Before shucking out a little over a hundred bucks for clamp kit, and router bits, I would like to hear some first hand experiences. Tell me the good, bad or ugly.
