For the use I bought it for, namely modeling, it is excellent. The two screws at the back need a little loosening so that the ball can rotate more comfortably, after that, when it locks, there is no issue.

The vise is obviously for small jobs at home or for electronics, etc.
If someone hits it with a heavy iron to bend it, etc. there is no way the vise will survive.
It has plastic covers on the jaws so you don't injure wood-plastic where they come out so they don't melt if you heat the piece they hold.
If someone doesn't need the rotation it provides, there are much cheaper vises.

* Be careful even when screwing it to the bench for fastening. If you apply force it will break even if it looks like it has thick metal. These cast ones are cheap and weak.

I have had it for 3-4 years, and I am very satisfied. I use it for light tasks. It changes angle as it rotates and overall it is a very useful tool. One of the tools that I appreciate.

I use it almost every day, it is small and convenient in size, it rotates in every direction and easily fits on any workbench

After a year of very gentle use, it broke without much force. There are also photos.
