    Expensive but it works.
  

*by A***R on Reviewed in the United States on July 21, 2024*

Expensive but it works, although not as good as a taytools jig. Try Taytools - they have a better jig which allows you to use the mag-switch magnets on your tools without having to use two-hands to activate.
