Meanwhile perfectly

Processing, geometry, load capacity of the jaws and the static friction of the rubber pad are excellent.
Savings have been made manifest in the only two point-like embedded magnets that hold the jaws on the vice. The magnetic adhesion is barely sufficient in most cases. But if you want to leave the jaws through a little on one side, for example, to have more space to measure, only still holds a magnetic point - or not; Any manipulation of the workpiece moves the jaw with an open vice. A stiff-shaped magnet, or at least a third, central magnet, would be good.
Addendum: As you can see, the manufacturer has now responded, and the part fitted with a strip-shaped magnet. Thus the criticism is no longer relevant, and the product deserves full marks.
