My experience in my limited dealings with their products is that it is really good - or really bad - and no in-between! The chinks are dishonest as hell to boot. If you tell them you want your purchases to be of a certain standard or specification - no problem, you round eyed devil! They'll put in a piece of paper that tells you what you want to hear, and you will take them at face value thinking that what they sold you meets API/ASME/CSA/CEC codes and regulations - and find out later that the little yella bastids pulled a fast one on you.
That looks to me like your standard
North American Jack-All.
Except for the break, mind you...
These were a dime a dozen when I was a kid and could be used to jack anything from heavy farm implements up to and including army tanks. Those things DID NOT BREAK. I will bet you a dollar to a donut that this jack came from China. How would you like to be under your car when this POS let go?
To be fair, the Chinese QA/QC and product quality is going straight up. The time will come when those guys are putting the Euros, Yanks, Japs and Koreans out of work - but they are probably going to kill a lot of people first.
Like many - I learned that in just about everything - you get what you pay for. For now I thank my Maker that I don't have to rely on Chinese made junk.
