Product review (4 stars): Works as advertised
Product was exactly as pictured, not with the metal reinforced center.  My guess is that it depends on the shipper as to which one you get.  Coupler was slightly tighter on the shaft then I expected.  My suggestion is to go online and watch the videos out there that use the screwdriver handle and hammer to get it on.  Took less then 10 minutes for this DIYer.
