Good construction and extremely convenient the Torx head. It doesn't come off the screwdriver at all.
Be careful if you use a very powerful screwdriver, especially an impact one. If the wood is soft, it will simply "bury" the screw into the wood, but if it is hard, it will cut the screw after a few strikes when its head enters the wood. It won't "jump" the screwdriver into the head like with Phillips when there is a lot of resistance.
