Great trimmer
This trimmer has lots of power, and the string advance works very well, thus far. The only comment I have is that I am a short person, so the shaft is a little longer than what I would like, but that is just one of many things we short people must deal with. Designers have to design for an average person.

Other than that, I really like this trimmer. No longer must I struggle with starting my old gas-powered trimmer.

A good answer to balky gas trimmers and low power electrics
Balance and ease of use is great. Initially I did not tighten the two screws which hold the guard in place, and it seemed to work better on keeping vines from making their way into the space between the head and the guard in that configuration than when I tightened the screws per the instructions. I have not done it yet, but am thinking about using longer screws there (maybe with metal spacer sleeves) so they both hold the guard in place and deflect the vine pieces down and back into the cord.

This is the best string trimmer I have used, bar none, and I would recommend it.

I am ordering this through Walmart and did not see the free battery added to order. Order # is 4481553272497 for Randy Briggs. I see you advertise free battery with purchase, do you not honor this when ordered through Walmart?
