I agree with everything "Neil W" wrote in his review. I was pleasant surprised by the quality and liked the quick action for quickly adjusting different width parts.I was also pleased that the vise opened 3-1/2" wider than advertised. As you can see in one of the photos, the vise opens closer to 3-15/16" compared to the advertised 3-3/16" opening. Before I close this review I thought I should check that the jaws are perpendicular to the base of the vise. I used one Table saw table for flat reference, set the whole vise on it's side and used a bench square I checked: 1. the base of the vise between the jaws 2. the face of the jaws and 3. the top of the jaws, open and closed All perfect measured, except for the fully open small vise. Otherwise the movement was perfect. Without a doubt this is a great vise for the price.
