I like the durability of the Bosch bits. Philips is phenomenal and I expected the torx to be the same. Unfortunately, they are a little sloppy in the screws and that causes some wobbling when used quickly. I compared Milwaukee bits of the same type and size. Milwaukee was much better. Phillips is totally bosch (I can stick a screwdriver in a horizontal screw and hang the screwdriver on the screw!). Torks, Milwaukee.
