Light Weight = Maneuverable
Style: String Trimmer
First time use today. It's works great. The light weight makes it so much more maneuverable than my very heavy 15 year old Echo weed line trimmer with heavy 58V battery. The Echo 58V battery died and did not want to spend $220 for new Echo battery with probably old tech battery. Debated on $300 EGO 56V trimmer and this corded 120VAC Black and Decker weed line trimer for $52. Also purchase a 50 ft AWG14 extension cord. The combination is terrific. Again the light weight is a revelation for me. The 6.5 Amp motor is plenty powerful. The thinner .065 line works well cut everything that needed wacking. The auto line feed works well. The length of tool fits me perfectly - I'm 5-4 so it may not be so good for tall folks. I extended to its max length. I wrapped the extension cord a few loops around the trigger handle and had no issues with cord staying on. Highly recommended with one could deal with extension cord. I don't see an issue with reliability and longevity. The electric motor seem well spec and strong. Really not much to go wrong with it. And no battery to deal with. For my very small yard it works great.

Great Light Weight String Trimmer and Edger!
Style: String Trimmer
I'm a 60 year old female and bought this because of the light weight. It was easy to put together, however, the instructions that came with it were terrible. It included only black and white images, with no written instruction. I found a great tutorial on YouTube that told how to assemble it and use it, and another on how to change the string. Buy extra string, so you'll have it ready! It does a great job on weeds and ivy. The edger is great. It is adjustable, but probably not the best for anyone taller than 5'6. It's noisy, but not so bad that it requires ear protection. I like that it's corded which makes it lighter and I don't have to fool with gas or heavy batteries.

Great weed wacker!
Style: String Trimmer
BLACK+DECKER Weed Wacker with Auto Feed, corded 14-Inch 2 in 1 String Trimmer Lawn Edger, Powerful 6.5-Amp.
I recently purchased this trimmer and really like it. It took less than a minute to set up, and the adjustable height and handle make it very comfortable to use. It easily rotates between a string trimmer and a wheeled edger for clean lawn borders. I did go through two spools of line for 7,000 sq. ft. of grass, but for the price, it’s a very impressive tool.

Serves its purpose-EDIT
Style: String Trimmer
Experience as of 8/1/24
Pros: ease of use, weight, power, price point.
Cons: There is no way to get out of spending a fortune on string. Manufacturer defect why this is so cheap & discontinued. Shame on them. I've tried everything in my unknowledgeable unprofessional experience. Silicone spray lube does help & plastic core has to be in like new condition - not even slight wearing. I've bought hardcore string, still rolls out too fast & gets stuck a lot because motor can't handle & tends to heat up string which causes it to bind. I've tried removing auto feed lever & auto cutter, worse. Kept past 30 days & tinkering voids my warranty. If $ spent on buying exorbitant amounts of string is not a concern, everything else is perfect. I have an old B&D from the early 2000s still kicking grass. I just hate batteries. So I can either buy a new weed whacker or buy batteries.
3.75 stars
Pros: Great power even with 200 ft cord (use proper cords). Works quickly & efficiently & powerful. The edger works outstanding. Used around chain fencing hard rocks & blacktop. Normal to high grass up to 12 in. adjustable Lightweight & easy to operate for a 62yo 5'2" female.
Cons: using electric cord was a pain for me but once get used to it no matter. The string automatically feeds but extremely fast. I believe it has to do with where & what you're up against. Many many times I had to stop & adjust the string roll. I found if ur careful about inserting properly & hearing the click it works better but again if you're operating under more than moderate conditions it seems to stick more & you have to adjust. That seems to be a design flaw in manufacturers use of cheaper materials.
The string it comes with is extremely short & runs out quickly. Based on other correct reviews I bought a B&D refill 3pack. Not the best either. I used all 3 rolls in 2.5 rounds of 1/4 acre back yard (hard conditions) & 1/8 acre front yard & blacktop edging. Better off buying bulk cheaper $ & restringing roll cores. I believe this also has to do with conditions of use and the B&D string is not any stronger than discount string. I purchased a bulk tougher string & will see if there's any difference in quantity usage.
This is not the best but not the worst. There are hardly any corded options for weed eaters but I was determined to stay with corded option because batteries are so unreliable these days. Product still a good value for the price. Disclaimer only sporadically using battery weed eaters a few years.
