Product is exactly what I expected but condition was not. Starrett provided excellent support identifying proper components needed for our inspection setup, even though non-Starrett products were included in the mix. Item was advertised as new, and probably was, but it was clearly an older product, having sat on a shelf in the sun for years. There was surface rust on the rods and the ground surfaces of the magnet base. It cleaned up with emery cloth but greater care should be taken for new product held in inventory. Selling price was higher than MSRP but total price with shipping was competitive for a NEW product.
