I pledged these two MetMo drivers on Kickstarter and am very happy with the finished products. Incredible design and machining! I converted both units to stainless steel barrels and one custom handle. The conversion went very well! I have a twofold rationale for buying the MetMo drivers: torque and control. I have stripped screw heads many times with my portable drills and as many times have not had the torque to complete a project. “Hats off!” To MetMo for solving both issues!
