It seems that these screwdrivers are very good. I have worked with them a little and I noticed a difference compared to other brands that I happened to work with. They have a nice handle and grip the screw well, although they are not magnetically bad. I have heard that you can make them magnetic, but I'm not sure about that. I will come back and update when I do it. It's worth it because these specific screwdrivers have an extension to reach a distant screw or to apply more force in a difficult situation. I haven't seen any others with such an attachment, maybe they are unique.
