Rated 5 out of 5 by from Works Great Solid construction. I appreciate the shoulder strap. The inner blade to trim the string as it extends is useful.

Rated 5 out of 5 by from Best trimmer Best corded trimmer I have. Better than Black & Decker, Ryobi. Only i don't like the white string loaded with the machine. Why a good machinegun goes with bad bullets?

Rated 5 out of 5 by from Powerful and Easy to Use This is 2nd time purchasing this trimmer, so I can use 2 different head attachments. If you don’t plan to use it daily (commercially) or have hours worth of trimming then you won’t mind the extension cord. No fuel to mess with. Plug in and go!

Rated 5 out of 5 by from No more gas I got rid of my gas powered products and no longer have to deal with emptying gas tanks, buying gas and treating gas that is going to sit during the winter. It does exactly what the gas powered did and less hassle.

Rated 5 out of 5 by from A Beast I have used this trimmer 3 times. Twice on the lawn and to edge, once to reclaim an overgrown area. This trimmer cut through everything with ease. Putting the string onto the spool takes some time to master, but it lasts once done. I am so glad to never have to buy a new battery or get rid of the old ones.
