If I need a large wrench, I would gladly spend $25 at Sears to get the quality. I will NEVER try to cut corners and save a few bucks, because my experience and also observation is that cheap tools will invariably BREAK or otherwise not function properly.
One simple question - how much does it cost to ship a wrench all the way from China and market it ? And after all of that is taken out of your $3, how much of that $3 went toward manufacture ? If it is chrome-vanadium steel, the material would cost about 25 to 50 cents. And you still need a little margin for the retailers markup. After freight costs, material, energy, tooling, marketing and retailers markup - damn - you can do all that with $3 ??? Really ???
The Chinese are dumping tools on us below cost and it is very obvious. They do not even understand that this is considered a trade infraction, and it may well be intended as a move to destroy western manufacturing capabilities.
Take your Chinese crap and shove it.
Made by slave labor and prison inmates - In China. Hah !!
I posted a comment about a vise I saw in Menards about 3 years ago. It was marked somehow so that it was recognizable. I saw the exact same vise sitting there almost 3 years later, and last week I checked and that same vise is STILL sitting on the shelf collecting dust. No-one is buying these things. Most people are not that stupid. Chinese vises will shatter like glass when struck with a hammer.
