First of all I think that the board buddy is a good idea. Safety is always an important issue with me. The board buddy is well made. In saying that I gave only 2 stars because the board buddy is a pain for people with metal fences. I have an expensive  biesemeyer fence on my saw . I'm  not about to drill holes and tap them in my fence to put in a track so I can use the board buddy.(fence has no pre-drilled holes ) I think that this should have been  something that Woodstock should have stated in their description or made an adapter . I had to go online and research this to fix my problem. I was very disappointed that I couldn't use the board buddy when I needed it.  I would not have bought the board buddy if I knew what I know now. I would have done  something else. Good wood fences are not  cheap unless you make one . It is something that a good wood worker can do and I'm not at that skill level yet. Not happy with Woodstock.
