I wouldn’t use it for high stress work, but it should be sturdier than the panavise, and some other retailers sell an “almost identical” vise, for a significantly higher price, that I suspect might be the exact same vise with a different name.
Unfortunately, it’s hard to tell if it’s the same, but I don't feel like spending $60-$80 for the other versions, checking and doing stress tests on the vises to tell.
The vises to need to be taken apart, cleaned, lubed, etc.
