I do woodworking as a hobby and on the many woodworking boards I visit, the SawStop company is universally hated.
They do have a good product that works, but it is an expensive retrofit. SawStop went to some of the major manufacturers of table saws to include their system as an option, the they all balked at the price.
Since SawStop could not get the manufacturers to to buy their system, they did the underhanded thing by going to the government. They submitted all sorts of exaggerated claims of gory accidents and tried to get the consumer safety arm of the government to mandate all manufactures of saws to include "only" their system.
Luckily, their sleazy tactics failed since most accidents were proven to occur due to the consumer removing blade guards, gross negligance, and not following the warnings in the manuals. SawStop ticked off the woodworking community and their sales dropped.
