Nice system, but you need to be careful of a few things:
1.Check the insert tools to ensure that the handle is locked onto the threaded rod. I have had 2 sets come loose. If the handle loosens while the insert tool is locked in the ball, you'll need pliers or vise grips to get the tool out.
2.DO NOT glue the Ball IT into the bottom of the hole UNTIL you are certain that the insert tool rotates freely, and by that I mean a nice, smooth, effortless rotation of the tool. Prep the hole as necessary with the included file, or use a bevel sander, to ensure this. Failure to do this will result in the slug hanging up in the Ball IT, and then you'll have to pull it out or drill it out. PREP IS EVERYTHING WITH THIS SYSTEM.
3. Keep it clean! Vacuum and clean prior to gluing anything.
If you do this, the system works very well.
