Excellent Edger in EVERY respect
First, I should point out that I own perhaps 20 different Ryobi battery operated tools. I have found them to be as functional as any corded counterpart. Second, I never run down my batteries all the way before swapping them for a new fully charged battery. Third, for this tool I only used 4 amp batteries. Smaller batteries may work fine but I had 350 feet of edging to do on a lawn that had not been edged in a decade.
The tool seems to have sufficient power if started in a trench with some other tool such as a knife. The lawn should be dry. Once started, the edger works as well as a 3 horse gas edger. I can not say how long a battery of any size will last. The best part of this product is ease of use which includes it's light weight yet powerful construction. No cords or gas. And it takes up no more room than a string trimmer in the garage. No string trimmer is a match for this tool. Even if purchased at full new price you will still feel it is a good value and that the quality justifies the price. The only improvement would be if some one else did the actual work. Each time you use it will take less and less time. Edge before you mow.
