It works perfectly with both LTT Screwdriver (black shaft edition) and with my Stubby Screwdriver. Made bit set with all the bit sets and the case I used was just a bit to small for the full size to fit in, but a stubby fit perfectly. Add this extension and now the stubby can be used in the places where the extra length is needed.

Feels solid!

Magnet is great. Easy to remove and replace. Very good for when you need just a little more reach.

High quality and strong magnet.

Does exactly what you expect it to do, extend the LTT screwdriver. Having used similar products for other brands in the past, I expected the fit to not be exact, or that it would feel wobbly on use however, i was very pleasantly surprised.
