Review on Top-choice BIIB Gifts: Universal Socket Tools for Men, Cool Gadgets for Dad, 🎁 Tools Christmas Gifts for Him – Husband, Boyfriend, Grandpa. Unique Stocking Stuffers for Men! by Colin Watkins

Very thoughtful design, looks sturdy. He's always trying to return to his previous state, so he'll keep any shape as long as it suits his head. The back is universal and I think it will fit any drill head. I think it's time to throw away 80% of the tools I'm not going to use anymore lol. Good option for almost $10
