Review on Efficient FastCap TAPER LOCK Taperlock: Enhance Your Projects with Quick and Secure Joinery by Tom Tucker

This is the best handpiece holder I have ever used, without exception. Holds square shank tips which tend to attach to screws making regular 1" sockets unusable for me as no other tip holders really gripped them. The tip hasn't come out yet until I want to and then they are very easy to remove. The magnet is also much stronger than other tips.
