Review: The Black and Decker BESTA510 is a KEEPER plus it's made in the USA 🇺🇲 - Well folks🙂 I have to tell you this has been a nice weed eater that cuts really good and it's LIGHTWEIGHT and it's powerful👍 and at a PRICE that can't be beat...it's way more powerful than some battery and electric weed eaters that I have.. like a Ryobi... And supposedly a commercial grade Ryobi $200 😤.. Anyway 🙂 This electric weed eater is very good and I'll take that PEPSI challenge any day 😀 when comparing it to some other weed eaters PLUS it doesn't USE LINE like other electric weed eaters that I've used.. at least that's been my experience.. This is a KEEPER weed eater from Black & Decker👍....it handles tall grass and even some hedge... though it probably shouldn't be used for hedge but it's TOUGH 😀 and better than any battery weed eater I used especially with the power and cutting... The power alone and convenience of NOT rushing through the job with the battery pack and charging ect imo is worth the cord drag 🙂... and much better than a battery weed eater or other electric weed eaters.. This just cuts better 👍... With MORE power consistently and constantly through the whole job... So in conclusion 🙂 the Black & Decker BESTA510 weed eater in my opinion is a KEEPER and this model has been around for a while which speaks for itself not to mention Black & Decker has been around for years.... This weed eater OVERALL (pound for pound ) is a solid performer with many mostly liking this weed eater and Black & Decker products overall.. Thanks for reading🙂.. I hope my review helps... and Did I mention It's made in the USA...🇺🇲..🙂...
Review: No problems all the way to the end of the spool - 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 desertcart 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.

## Questions & Answers

**Q: Does this trimmer require a two-prong or three-prong power supply?**
A: You can use a three prong extension cord. It only fits one way though. So if it doesn't fit flip it over and the cord should plug into the trimmer.

**Q: What is the process for line replacement?**
A: When replacing the line, use only 0.065 inch (1.65mm) diameter round line. Other diameters or shapes may degrade performance or cause damage to the trimmer. Unplug trimmer. Remove the empty spool from the trimmer. Remove any remaining cutting line from the spool. Make a fold at the end of the cutting line at about 3/4 inch (19mm). Feed the cutting line into one of the line anchoring slots. Insert the 3/4 inch (19mm) end of the bulk line into the hole in the spool adjacent to the slot. Make sure the line is pulled tight against the
spool. Wind the cutting line onto the spool in the direction of the arrow on the spool. Make sure to wind the line on neatly and in layers. Do not crisscross. When the wound cutting line reaches the recesses, cut the line. Fit the spool and cap onto the trimmer.

**Q: what is the wattage of this trimmer?**
A: The wattage is 780W

**Q: What type Of spool do it use**
A: It's just called AFS Automatic Feed Spool with 0.065in line. Works great!

### ⭐⭐⭐⭐ Handy until I can purchase a mower
*by T***E on June 26, 2025*

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.
