Query: not only bad design but dangerous to use!

Automatic feeder does not work properly!! Trimmer ran out of string before my trimming was completed the first time. It cut 1/2 to 1 inch pieces of string hurling them like shrapnel giving cuts all up and down my legs. I showed the man at Lowe's what had happened when i returned the item....thank goodness no one else was in the area...DON'T RISK IT...
