    Great extension set!

    I am totally impressed with the quality and range of sizes in this set. They hold the socket very tight meaning you will not leave it on the nut when removing. They work really good as a non-wobble with little play and provide a good amount of angler reach when used in the wobble mode. One thing to note is these work the best with sockets that have a single horizontal retention groove rather than the try found on modern Craftsmen and others with this design. The Duralast, Proto, and older Willams sockets I have offer a smooth and large angle (10 degrees) offset to get into those cramped places compared to my Craftsman sockets. I really like these and enjoy using them, very happy with my purchase.

    Pros: Holds sockets tight., Large size range, Works as a wobble and regular extension all in one, Fantastic value!

    Cons: The knurled grip area could be larger and higher up

    Impressive product!

    Have never used wobble extensions before and picked these up by mistake. I tried them anyway and am so impressed. The give a little bit of leeway without become like soft spaghetti. AND .. if you push them all the way in, they'll become rigid extensions. Awesome find!

    Pros: Able to wobble AND attact rigidly

    Cons: None yet
