This is a clever wrench idea. This is a great ratchet wrench. I'm impressed. I love the idea of having a wrench to control them all, but it's a lot heavier and bulkier than a standard ratchet wrench. Larger sizes are also uncomfortable to use as the spring action pushes the wrench away from the bolt. This 8-in-1 ratcheting socket features a versatile, precision 12-point head that is thickened for consistent strength and high torque, and a rounded inner arc protects the fasteners. With no play or slippage, they fit perfectly onto the appropriate nuts and bolts. Ratchet size 8mm, 10mm, 12mm, 13mm, 14mm, 17mm, 19mm and 21mm. The reversible ratchet wrench has 72 teeth and only requires 5 degrees of space for each turn, greatly speeding up the workflow with less effort. There are no sockets to swap, so you can work with one hand. It is made from chrome vanadium steel with a heat treated body and thickened head for maximum strength and toughness. Mirror polishing not only protects against rust or corrosion in continuous use, but also enhances the appearance. For ease of use, there is a forward/reverse switch at each end that can be quickly released to change the direction of rotation of the ratchet. This is a good addition to my toolbox, I would recommend it
