Pros : this is a wonderful way to stretch lead came. I like the way that you attach it to the end of your work table where it is out of the way, but yet handy enough to use. Just 1 tap with a hammer to set it & one can pull it to stretch it with no problems.
Cons : there is just 1 hole to screw it into the workbench. it would be nice if there was 2, but 1 seems to be working.
Other Thoughts : it comes in very handy to stretch the lead came out, especially when using it a lot.
