Review on 🔧 11.5 Inch Flexible Extension Shaft with 10 Drill Bit Sets, 1/4'' Hex Head Magnetic Connect Drive Shaft Tip, Drill Shaft Flexibility, Batch Head Connecting Rod with Multi-angle Functionality for Enhanced Work by Brandon Daughenbaugh

Everything was going well until something happened. I managed to get 6 screws out before the tip broke off the spring inside. Normally I would write it on "I get what I pay for" but I couldn't even finish the project. The problem lies in the design of the mechanism. It is essentially a spring that is screwed into the bit holder by friction. Well it's a twist mechanism and it twists right out of the bit holder. If you have something that needs multiple uses I would avoid this product. There is no durability at all and you are left in the middle of a project waiting for a better replacement.
