I have 2 sets of these, and they work flawlessly!! They stay in place on the screwdriver, or run it up and down the shaft a few times and it will magnatize the screwdriver. Have not used it as a bit holder, just to magnatize my screwdrivers. I love the innovative products of Olsatools that I have been receiving as of late.
Thanks for the feedback, Jonathon! We're happy to know you love these bit holders! We appreciate your support!
