Has a little more play that I expected while open, but clamps down securely, the rotation is nice and smooth, so overall, it works great, especially for the price. DM
Excellent value for money. It does the job of holding various pieces with the many attachments. Size is just right for setting cabochons. Build quality is good. Rotation adjustment can be improved by adding a small spring between the grub screw and the nylon rub block.
