This could be a good product if two things were improved. 1-It needs to be 150mm higher as there isn't enough height to comfortably hang a bobbin holder down off it. 2-It needs a grub screw in the bottom back of the base to lock the height stem firmly in place because it wobbles around when using it. If these two issues were addressed the vice would be near a pro tool. In it's current state it is only a cut above a kids toy. I'm sure these two things would cost next to nothing in manufacturing and would vastly improve its ergonomics.
