Review on Yakamoz 11 Piece Magnetic T6-T40 Torx Head Screwdriver Bit Set - Security Tamper Proof Star 6 Point - Drill Bits - Tools with 1/4 Inch Hex Shank, 3 Inch Length by Theodore Huynh

I had a whole bunch of Xbox 360 wireless controllers that I wanted to disassemble and clean. I had a small L-shaped key for the security bits, but they are. I tossed one of these into a cordless drill and quickly disassembled, cleaned, and reassembled all of the controllers. However, do not use them for regular Torx screws; The center hole makes these bits much weaker than standard torx bits. I haven't broken anything from this set, but I have broken several torx security bits from different manufacturers in the past.
