When I was an automotive technician for Chrysler, Jeep, and Dodge there were just some tools that were necessities that I just couldn't live without. The craftsman metric ratchet wrenches were one of those tools. These wrenches made my life and my job so much easier, they saved me so much time which in the automotive business, time is money. Some of the cheaper ratchet wrenches don't have a lot of teeth in the ratcheting mechanism and you have to turn the wrench a lot to get it to grab, so it makes it hard to get into tight spot and still turn the wrench. The craftsman wrenches have a lot of teeth that grab with the slightest turn so they are great for getting into those hard to reach areas. The wrenches are chrome coated and wont get scratched or dinged up like other cheap wrenches. Also, the craftsman wrenches are durable and strong, I've put quite a beating on my set of wrenches over the years and they are still like new. I'm out of the automotive business now but I still use my craftsman wrenches around the house. They are great for everything.
