They're largely junk. Because of my vise website I get calls all the time about people with broken vises, and it's usually one of this style (similar design, made in China) or the rotating style that people break.
Since seating bearings was mentioned, I'll point out that a vise shouldn't be used to press bearings....they simply aren't made for it. You can break even a quality vise trying that. Sure, a big vise can be used to press in small bearings, but it's hard to know where the safety line is. The other thing is I've have had people tell me they were simply tightening the vise on a piece of steel and had the dynamic jaw break off cleanly....no cheater pipe, or anything like that in use. Both of those were listed in the reviews posted of these vises.
In the long run you'll be better served if you can find a decent used quality vise...most anything U.S. or U.K. will be good. Also, don't get tricked into thinking you want/need 5" or 6" jaws. They put them on cheap vises to make people think they're getting a big, strong vise. A quality U.S. vise with 4" jaws will do all the work that a Chinese vise with 5" or 6" jaws will do, and not break.
Most fabrication/welding shops I go to have 4.5" and 5" jaw models and they don't need any more than that. Those are typically 65-95lb vises.....weight is a better indicator than jaw width.
For the folks in areas that don't have a lot of vises you can even buy some reasonable vises on eBay and have them shipped without spending hundreds of dollars. I'm getting ready to ship a Reed 105 (5" jaw, probably 75lbs) to a guy down south and he's going to get it for under $100....it's possible.
