Rated 3.8 out of 5 by 35 reviewers.
Rated 4.0 out of 5.0 by great The trimmer works great as a trimmer as well as an edger. The fact that the line lengthens itself is an incredible feature. I love this trimmer and would recommend to anyone for residential use and looking for something cordless without the need for fuel. The review above holds a little bit of weight, although, much exaggerated. The two batteries is enough to cover my entire property, which is 60ft X 120ft. Charge on the battery could be an issue if trying to stretch it for a larger property or if your grass is on some sort of steroid and you have to trim every 12 hours and can't charge the battery.

Rated 1.0 out of 5.0 by Not a happy customer This product is by far, not worth the money. To begin with, it took 8 hours to charge each battery, 16 hours. Then it only took 15 minutes to drain both, with trim left undone. I had to get out my old gas powered trimmer to finish. The manual says it takes 8 hours to charge a battery, but if they would bother to print that info on the box, or in the write-up, along with the fact that a battery only lasts 7-8 minutes, then people would not waste there time bringing it home and having to return it, which is exactly what I will be doing.

Rated 1.0 out of 5.0 by Poor performing and Not Worth the Money Quality is poor: 1)edger guide does not work properly and is in the way for weed whacking 2) lithium battery is horrible...short life..I used 2 batteries and did not finish my small lawn! With my old device and 18v batteries , I could do it with 1 battery!3) handle placement and length of adjustable pole is uncomfortable for use! I am extremely disappointed and angry that I wasted my money,especially since I bought an extra charger and now plan to never use this product or their 20v lithium batteries again....will now shop for another brand,even though I have been loyal to Black and Decker since 1992.This product is total junk!

Rated 5.0 out of 5.0 by does it exactly right. lightweight-easy to manuver, always have 1 battery charging. can swap out a battery easily and i get the whole yard done with the 2. I have 3 acres to trim and am darn glad to have it. August 18, 2012
Rated 4.0 out of 5.0 by easy to use, lightweight, great for very small yard love this product, except the battery life. i usually have to switch the battery before i finish the front yard. it is a small plot, but due to edging, i seem to run out of energy quickly. the weedeater and edger are so easy to use and i love the automatic line feed. the battery could be improved though. i can fully charge it the night before, yet when i unplug the charger, it runs down without use in a number of hours. so glad it came with two batteries.

Rated 5.0 out of 5.0 by Good Little "Weed Eater" A nice little cordless weed eater. I deliberately purchased it because it was cordless and had two batteries. I have not had occasion to use it but one time but it did great. So far, I really like it. I am sure that I shall get quite a bit of use of it. October 14, 2014
Rated 2.0 out of 5.0 by Feels Cheap I bought this combo kit because I had purchased the B&D 20v Li-Ion Drill earlier this year and it has been outstanding. I liked the idea that the batteries were interchangeable. This combo kit is EXTREMELY light duty and feels cheap. The trimmer only lasted about 15 minutes on a fully charged battery. They give you two, but by the time I was done trimming and halfway through edging I had used both batteries. I had to pull the battery from my drill to use the blower. I live on a corner lot, so my lawn is a bit larger than the neighbors, but I expected this product to at least get to the end of my weekly maintenance. It did not. I am returning this product and will buy either a plug in or gas powered trimmer...and a broom. May 27, 2012
Rated 5.0 out of 5.0 by Good Purchase I am an older, female purchaser and found that this trimmer was well balanced and light enough for my 5'-2" body frame. It was good that the trimmer came with two batteries. I always have a spare on the charger. Good product for my purposes. Oh, one of the things I like is the low noise level. For me, cordless electric was the way to go. July 30, 2014
