They're fine

Look, honestly I bought these because everyone on Instagram was hyping them up... they're good, not great. They're very limited in the size range that they can fit on, and yes you can buy the next size up/down, but that's another $60-$70 to spend... anyways, I like it and will continue to use it, but I don't know if I'd buy it again.

Joker self adjusting wrench

This wrench was as a good as any of there other wrenches and worked as advertised. The price was a little high that was the reason it did not get the 5 stars, but it did help take a couple wrenches out of my service bag, and anytime I can have less tools to carry and still be able to accomplish what I need to do is great by me.

Wera has done it again

When you think of German made tools, the first word that comes to mind is Engineering. German Engineering is known throughout the world as a trait you definitely want in a tool. Wera has found yet another tool to improve. And these Joker 6004 designs are a huge improvement on the Adjustable wrench market. The comfort, and function of this wrench is perfect. This has become the first tool out of the bag on most of my jobs. It took a few uses to get my muscle memory adjusted to how this tool performs, but now it is an extension of my hand. I can't wait till they release the medium and XL sizes in the USA
