Review on Large Push Block For Woodworking - Woodstock W1401 by Craig Galante

I cant for the life of me work out why 4 users gave these 5 stars. The ones we have are extremely dangerous as they dont grip the surface properly. Applying even more pressure to counteract this causes loss of control and a VERY real danger of slipping into a jointer blade. I have never had problems with a Shop Fox product before and have a shop full of their products. They wouldnt have even half the gripping power of say Rockler or Bench Dog.
