The packaging and the fact that it only included one battery is a pretty good indication that I was sent a refurbished product. I purchased it as NEW. The user manual was pretty clear, however, as the print was small. It would have been nice to have available a download version. (I searched the Black & Decker website but couldn’t find one.) I use the tool to edge the lawn and trim around trees and garden. While not as powerful on high setting as my old corded model, it was adequate for normal lawn and yard. I would recommend having 2 batteries as it started to run down towards end of my work. I used it on high settings most of the time. I did have trouble getting the grass growing from cracks but got it close enough. Patches of high weeds took work to get them cut down. I think if I worked at getting the angle ‘better’, I could have done better, however, as this was my first use and I wanted to be sure I had enough battery. Although I am disappointed it seems refurbished and comes with only one battery, it seems to do what I need and I will be keeping it.
