Kobalt is has taken Double Drive technology and put it into a ratchet. The Kobalt Double Drive Ratchet operates like a normal 3/8″ ratchet except for the twisting and extendable Double Drive handle. It has a lifetime warranty and our set came with some bits and a few sockets. The ratchet will allow you to get into places where other ratchets don't dare.. When you get into an area that you cannot move the ratchet you can twist the handle for Double Drive action. This is a great idea, however when you have a really tight nut you cannot get the same breakaway torque that you would with the traditional way.
When you are not in a tight area and use it like a normal ratchet the handle can be extended to provide massive toque. On free moving nuts the double drive twist will give you twice the speed, then you can snug it up with the handle. The Kobalt Double Drive Ratchet is borderline gimmicky to some people and for some it is perfect for their application. Either way it makes a great gift.
