DURATECH 3-Piece Adjustable Wrench Set, 6-Inch, 8-Inch, 10-Inch, Cr-V Steel, SAE & Metric Scales, for Home, Workshop and DIY

If you want an adjustable wrench that is high-quality, this is a great choice. These have way less "slop" in the mechanism than most adjustable wrenches due to good quality production tolerances and also due to the excellent design of the adjustment screw with 5 points of contact (whereas the normal adjustable wrenches have only 3 points of contact). The wrench holders its size well even with some shacking and movement. They have the markings for inches and mm, so you can dial quickly to what you need. Probably the only better adjustable wrench available is the Milwaukee wrenches which have 6-points of contact, but are somewhat more expensive than the SK. I've used these SK adjustable for many jobs and I'm very happy with their performance. They are better than Craftsman, Irwin, and virtually all other brands that I tested and gave away.

S&K make great tools and if you ever do have an issue they will help you.

They seem pretty decent for Chinese Made Adj Wrench , or was it vietnam? I forget

I bought these and the 12" separately, and they are all very very high quality, just what I was looking for.

Quality wrenches.
