    Is a joke. It rounded the nut and I’m still going to buy the complete set to see if it’s all a joke.

    Surprisingly Useful

    Didn’t know what to make of this at first but it turned out to be highly useful for a job on my garage door opener chain where a socket just wouldn’t work. So, very good in tight spaces and no fumbling with a traditional adjustable wrench.

    Awesome little wrench

    There is some minor technique to learn when using it, but this design is wonderful! Once you get it going, it works like a ratchet. Which means I can leave my heavy ratchet set back at the office. The cool "toe-hold" feature means you can get into tight spots. I needed one this size and the small as well. I'm a global field service engineer. Anything that adds capability and lightens the load is great in my world.
