Top quality battery operated Black & Decker Cordless String Trimmer ; . Assembly was very easy, only a couple pieces, not too heavy , versatile. ; What is great about the Black & Decker battery operated tools is that you can use the 20v battery with other Black & Decker tools that are out in the market. also, an extra battery can be purchased.. Tool as good instructions if you need it .

Light weight and easy to handle

Style: 20V String Trimmer Kit

This is my second one. Light weight and easy for me (old woman) to handle. Unit rotates so you can edge. The old one lasted right at 6 years. My old batteries work on new unit also. I get the one with the wheel which makes it much easier to edge. This one auto feeds and my old one didn’t. I don’t know how I feel about the auto feed. Another brand I had before with auto feed stopped working. That was a pain to manually feed. Have only used the new one twice

Very disappointed

Style: 20V String Trimmer Kit

This is my second black and decker weed eater. Very disappointed. The first is at least 10 years old and was more powerful. The only reason I replaced it was because it stopped feeding. The BD people told me they didn’t make parts for it anymore. I’ll not buy another. Not as powerful and the battery lasts maybe 15 minutes.
