Auto feed

How is the auto feed on this? I currently have an older Black & Decker Grass Hog with an auto feed spool and it is horrible. No matter how careful I am to reload the spool, it never auto feeds properly or it jams. So I dread using it and I'm leary of getting another trimmer with an auto feed spool.

Customer Reviews

20-Volt Max Lithium-Ion 2-Speed String Trimmer is rated 4.3 out of 5 by 92.
Rated 4 out of 5 by from Solid for my Yard I hated dealing with my corded trimmer, and I don't have a big enough yard to deal with a gas trimmer, so I gave this rechargeable B&D a chance. I have a small yard, and it works well. For most trimming I use the low setting to save battery life, and it does just fine around the rocks, poles, posts, etc. I only switch to high for edging my sidewalk. I can get probably 40-45 minutes out of a charge, so I can't trim the yard and edge the sidewalk. But I can do one or the other. The auto-feed is great and becomes a time-saver; I'm over dealing with bump-feed. I waited a couple months to review this, to myself time to assess it completely. I'm happy with it.

Rated 5 out of 5 by from Received this for Father's Day Already had the hedge clippers that use the same battery (love those too). This thing works great. Got a 1/2 acre lawn and use up a battery and a half usually. Has more power than you would think. I use the edger wheel a lot for the driveway, walkways, and front curb - its a nice feature. Two seconds to flip from edger wheel back to normal trimming. This trimmer will cut into the dirt nicely to give you an edge. Not quite as powerful as a gas trimmer, but the ease of use / low maintenance factor of this thing is more valuable to me than having the strongest trimmer on the block. Would definitely recommend.

Rated 5 out of 5 by from black and decker 2 speed string trimmer. Its now fun to do my yard work with my new trimmer. Its light weight and very easy to use. I can get through my chores in half the time. I love how the trimmer lengthens the cord for trimming automaticly. No puling need to stop work to pull or adjust things. And changing the spool of cord is a snap! Now I have time to do many to do other things I want. Instead of slaving the trimming is fun.

Rated 5 out of 5 by from String trimmer purchase The trimmer came in great shape and was easy to assemble. After charging it worked great and had some nice features like edge trimming ease, adjustable handle and telescoping shaft. The best is that it is light weight which makes it easier for me to use.

Rated 5 out of 5 by from As expected I bought this because I wanted mobility and don't have a lot of areas that weed eating is needed. I was not disappointed as I was able to edge my entire front yard and weed eat my back yard. Great product for the price.

Rated 5 out of 5 by from Excellent product! This product is lightweight and easy to use, and does a great job! I like that there is an option to save battery power when doing light work. Edger works great--nice feature! Highly recommend.

Rated 5 out of 5 by from great trimmer so far! I bought this April 3, 2016. I charged the battery (it took 5 hours). It rained and snowed after I bought it, so I didn't get to use it until April 16, 2016. I got about 150 feet of edging done in 40 minutes and the battery died. I think it was because I charged it two weeks earlier, and it must have discharged a bit (at least I am hoping that is why it only lasted that long). It did a great job edging. It's easy to use, light weight, seems to be sturdy, and it doesn't vibrate like my old electric Weedeater did (RIP after 29 years of service). The second charge took a little over 6 hours. I hope this one lasts at least half as long as my Weedeater did. It has a lot of power on the #1 setting. Fingers crossed this baby keeps going for a long time.

Rated 5 out of 5 by from Amazing little trimmer! Did my research and read reviews. I didn't believe that this little thing would work that well being only one string (versus the two string gas powered hunk of junk I had before that I thought did a good job) but I am amazed at how well it it trims and edges. The only thing I will say against it is the battery life and re-charging time but I knew that going in. As long as you don't have a huge area to do or are not in a rush to do it then it will work just fine. I'm going to buy a second battery and a better charger and then it will be perfect!
