    No problems all the way to the end of the spool
    Style: String Trimmer
    I had an old Greenworks string trimmer that I found in the basement after I moved into my new home. Maybe it was just old, but the auto-feed didn't work well, the line was always running out, and I spent more time rewinding the spool than cutting down weeds. I had almost lost my faith in string trimmers entirely. You can spend $300 on one, but how much better are they? I didn't know. This Black & Decker was only $50, and although it's corded, my roommate convinced me it was worth not having to do the dance of recharging batteries, plus having full 110v power. Some (easy) assembly required out of the box, and this thing was basically plug & play. I did read through the owner's manual first, which gave amateur me some confidence through a few helpful tips. I use it not only for cutting down weeds, but also for cleaning out weeds from the cracks in my sidewalk, and the edger wheel is very helpful for that. More importantly, the line had no problems all the way to the end of the spool. Faith restored, there are good string trimmers in the world. That being said, be aware that the line it comes with isn't very long. My lawn is medium-size, and it ran out about halfway through. The Black & Decker replacement spools are $10 / 30 ft (much longer), but it goes through line, so this could really add up. Replacing the spool was easy, and I was able to finish my lawn with plenty line to spare. A quick search on Amazon reveals off brand spools at $15 / 12-pack. I haven't tested them yet, but the price difference is so great that I'm going to give them a chance.

    Handy until I can purchase a mower
    Style: String Trimmer, Style: String Trimmer
    I've used this thing heavily 3 times now. I need a mower but haven't had the spare money for one yet so this is what I'm using! My yard is just under 1 acre. I'ma list some pros and cons I've noticed in my good use.. Pros: it works.. really well! As you can see I live in Florida so grass grows super fast in our rainy season if I slack just 2 weeks oh my.. the power is strong, it's easy to work. Auto feed is a big help. I bought extra when I made this purchase I can go through about 1-2 rolls throughout the whole yard. Cons: the wire. It gets in the way so much and my large yard I use a 200 ft cord but that's not always enough so I can't complete my job completely but enough I'm happy with. When the auto feed is low i noticed it constantly over feeds the line and that honestly hurts sometimes! It's and easy fix but after doing it 5 times you're over it. Id just put a new one on but I feel that's just a waste. In the future I will be replacing mine to get rid of the wire.

    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.
