Don't go with a Troy Bilt, I'm on my 2nd one. You might ask why do you keep buying them. Its because I have a lot of money in all the attachment. Be sure to do your homework before you purchase an All-in-one because you get trapped with all of the accessory purchases. I first, I was ordering parts. New shaft=$30, New coil=$54 and then wised up and just got another New trimmer unit = $100. When I first bought, I thought it was great and convinced my family to get one. Now, I have one operating unit and 3 units for spares for parts. My father and brother gave me there's after theirs broke. One has a bad coil and the other, I'm not sure of yet.
