This product reappears on eBay with presentations that claim "Butch Harmon" endorsement and support. A video is included. However, the product is bogus. *** There is no connection to Mr. Harmon other than an unauthorized use of his name and image. *** The swing video has no connection whatsoever with the Harmon swing. This is not the swing Tiger Woods used in the late 1990s and early 2000s. *** Also one of the "laser" attachments in the one I bought did not work at all. *** An old, likely illegal product. Useless and a very bad deal.
