I liked the height of my previous worktop, the vacuum vise is better but this one isn't bad either. I have attached a picture as my previous one is a regular type. Basically everything is the same except how you adjust the angle of the jaws; Yost is much better. However, it was a pretty big problem. The vise head turned on its mount. The stamped Allen key didn't fit the shaft at all. I had to disassemble the shaft and solder it into a hex. It only took 5 minutes but was quite annoying for a brand new item. The head on my old vise attaches the same way, but the stamped bushing is tight. Now it's rock solid and the vacuum is very strong as long as the surface is smooth.
