This is an excellent bending machine at a very reasonable price. The measurements are quite accurate when compared to readings from a L&L gauge. I'd say it is within 1/2* when compared, which is about all that is needed to make accurate bends followed by confirmation on the L&L gauge. The machine has a lot of clamping strength and I can see a lot of years worth of use with it. There is absolutely no comparison of the ease of use and clamping strength when measured against the GS Club Bending Vise, though that unit is but a fraction of the cost of this one.
The only issue I have with this unit is when I attach it to the universal stand. The bending bar will hit the sides of the stand on lower lofted clubs that need to be bent stronger. This is easily overcome by reversing the bar, but that's not easy to do when mounted to the universal stand, as your body position will put you in a bad position and the stand will begin to tilt. It seems like a fixable issue though.
