Bought this and did not open until I completed my new workbench, the first thing noted is there are no instructions for installing the vise and no template for drilling the holes. When I placed it on a flat surface to make a template noticed it was high in the middle and rocked back and forth, I ground done the surface to make it flat. I looked fro and found an installation video on YouTube provided by a customer of Vevor not Vevor. I t would have been extremely difficult for me to install this if this video was not on YouTube. It seems to be a good vice after modifying and installing, Vevor should provide a template and installation instruction with every vice or at least a link to instructions.
