Review on TEKPREM 1/4 Inch Magnetic Bit Holder: Securely Grip Bits & Screws with Strong Magnet Tip and Non-Slip Handle (190mm) by Sean Perry

Feels solid, perfect length, magnet works. That's exactly what I need. It allows you to use all square drive bits etc and also allows you to attach 1/4" square sockets to a square stopper bit with a hex. I also have a 1/4 HEX to one 1/2" hex. An adapter is on the way so I can use 1/2" square heads. I also have a 105 degree 1/4" corner adapter to use corners. Pretty groovy. EDITI used it for carpentry work. Astonishing. It's really easy to generate torque with it thanks to the wide handle and rubber grip. Tolerances are great... when you put the bits in, they don't wiggle. great quality I've even played around with putting ammo in it (but didn't drill any holes) and it's nice.
