We had one of their walk behind trimmers. Worked great as a trimmer, they offered a circular blade attachment and we got it. Worked great cutting down little saplings until the bolt that held the blade in place broke while I was using it. Before I knew what happened the blade shot back into 1 tire, jumped to the other tire and shot out away from the machine some 20 feet. God was watching over me that day, if it hadn't ripped those tires apart it would have shot straight into my feet. That was 8 years ago and to this day I will not use it.
