Klein does it again
These are heavy duty and designed very well. They are also very large in size which I was not expecting. They are easy to hold onto and are quite versatile. For context, I work in IT and have used these a few times for installing monitors on dental arm mounts and they have worked flawlessly. Definitely worth the money. Klein is my first preference for tools in general because they have been consistently high quality tools for a great value. They also tend to have options that are more aligned with what I am looking for instead of having to buy a larger kit than I need or buy separate kits to get what I need.

All Your SAE Hexes in One
This is a surprisingly large hex set. That said, it's an extremely sturdy hex set. I don't think I could torque out the frame or the individual drivers before I start stripping bolts. The black finish didn't last the first bolts turned, but the metal underneath is completely unmarred. This thing has every size of hex head I've ever seen, and a couple that I haven't, ranging from diminutive to gargantuan. There's no locking feature, but it has solid enough tension that it doesn't really need it.

It's big, beefy, and solid tool to use.
Great tool, it's big, sturdy, and solid hex wrench multi-tool. Used this to assemble a big and didn't have any issues, Easy to grip and didn't slip or cause me to mess up. Would recommend.

Worth the price
This is significantly larger and heavier-duty than the typical, less-expensive key set. Worth the price.

Solid tool, good value for the money.
These are much, much stronger than similar folding hex key tool from Wiha. Somewhat chunky, but I think that serves to help with the strength. Very happy with the purchase, these are one of the most useful tools in a toolbox these days with how many things around the house need hex keys to be assembled these days.
