I just got my first Edgit this week and love it!!!!!! I can definitely see the attraction to it and want to get a couple more for my employees to use. My only concern is my liability exposure!!!!!!! My thought is this: I have removed the factory installed safety guard and replaced it with a off market device designed to produce a better edge. Yes I realize it is bigger but it doesn't have a lip like the factory guard and it requires the string to be let out farther the the factory guard. When I talked to Scott and Edgit he gave me a lot of what he thought were logical reasons why it was better / more protective than the factory guard but no official of documented studies ( ei. anything that would cover me in a law suit ). Yes all my employees are required to use safety glasses but they are still going to get hit in the face. Any thoughts??????????
