As soon as the trimmer arrived, I charged the batteries, assembled the parts as the instructions said. First I tried the wired attachment, I liked the power of the motor, but not even 3 minutes working carefully, the wire disappeared, flew away I didn't know where it went! Attached a new one, almost at the same few minutes running, the wire was gone! I tried the 3rd wire and it's the same, failed! Next, I loaded the plastic blade, no idea where the blade parts went when it broke in just a minute run time. Do you think I will try the metal blades and the saw blades like? I don't want to hurt myself or anyone. I am just curious if you have any suggestions?
