BLACK+DECKER20V MAX Cordless String Trimmer and Edger with Spool, Battery and Charger Included, 2 Speed, 12 Inch (LST522)

I hardly ever send in a review, but this trimmer deserves a 10 star. I had an older model for years that I inherited, so might have been 5 to 10 yrs old. Worked great but one day the string mechanism malfunction, probably an operator error. This newer model has a wheel to make trimming straighter and lighter. I am so pleased w this model for my 1/3rd acre lot. I am a master gardener, so I don't want to fuss so much w trimming around the fence, garden, bird feeders, drive and sidewalk, so I can spend time working in community gardens. This battery operated trimmer made short work of my trim needs. I would recommend having 2 batteries. Especially if you have the Black and Decker Blower... which also works like a charm and is very lightweight. Thanks Black and Decker!Oh, BTW, I could not find this model at Home Depot, Lowes, or Walmart... sold out? Who knows.. Amazon was the same as any list price of other stores, plus free delivery! Yay!

My neighbor recently convinced me to purchase this trimmer. For the past 9 yrs I’ve been using a Husqvarna 4cycle trimmer which is very powerful and has performed great. But I needed a trimmer that could be used to form a nice demarcation between the concrete and grass…and also around flower beds. I would have to tilt my Husqvarna to achieve this but due to it’s design it would leave a “sloped” edge. This Black and Decker performs beautifully. The built-in wheel makes all the difference in the world as well as the ability to tilt the trimmers head (by turning the handle). The wheel helps stabilize the trimmer so that you can get a nice, neat edge and it even does very well around curves. It’s also much lighter than my other trimmer…very easy on the upper body. I have only used it once (today) but was so impressed I wanted to write this review. My neighbor has had his for years and it’s still going strong….so I’m not to worried about durability. If you need a trimmer for cutting down really tall grass or saplings, then a heavier duty model (like my Husqvarna) is probably what you should purchase. But for normal use, this trimmer will be just fine. I may even purchase an extra one just as a back up in case this model is ever discontinued (hopefully not). One more thing…it would be a good idea to go ahead and get an extra battery as back up. Hope this review helps.

First..I didn't know jack about trimmers until I needed one. Did little research and realized that paying a little more for automatic feed is worth it. So I bought this Black and Decker instead of the cheaper suggestion without auto feed.Second...every review is right. Auto feed is a stress and headache saver. I haven't had one issue with the feed. You will regret buying a trimmer withOUT auto feed if you do.Third...battery. hmm...the reviews are right here as well. 20V is not enough if you have a lot you need to trim in one go. I can edge my entire front yard and trim around the fence in one charge. I was also able to trim around the tree stump. I did all that with it on extra power which was a great bonus. Made short work of the weeds that needed to go. So the 20V will work for my every weekend chore of trimming. If I do buy the blower I will pay for the B&D one that comes with a battery so that I can have an extra battery as they are interchangeable.I do wish that the trimmer handle was a little longer. I need about 4 more inches of length. I do like the light weight and balance because I have a bad shoulder and this trimmer has been easy to handle to get the job done. The volume isn't so bad. Quieter than I thought it would be.All in all...very easy to use and control for a first time use trimmer. I'm happy with it...

Had this trimmer about a year now or or longer works great. Have no problems with it battery stay charged well. I highly recommend it.

5th year now and I am alive, and still extremely happy with trimmer. I have bumped my stars to 5.All that I wrote before still applies,I am older man with respiratory problems and I need all the help I can get maintaining the yard in the hot summer heat. This trimmer and my new small ride-on mower are my new two best friends.1. No extension cords. What a wonderful freedom. (Circle a bush twice then go straight to the next !)2. Lightweight. The shaft and work head rotate for sidewalk edge trimming and that's it. No head tilt or similar extras. I figure that's what keeps it lightweight and in the cost range it's in.3. I bought this trimmer for trimming grass around places a mower can't get, weeds before they reach 3 feet tall and trimming sidewalk edges. It does that just fine in less than half the time it took with my old corded whacker.4.Battery- I have busy yards with playthings, a garden, bushes, trees and flowerbeds with borders and more. They are fair size yards and it uses about a battery and a half. Unless you have small yard I suggest you buy an extra battery also5. Dinky Charger. Yes it comes with a slow dinky charger but once again I believe considering the price range warrants a no star reduction. After purchase I found out I could use my Porter Cable 20v fast charger after a small simple battery alternation. It's a convenient, but I believe with the two batteries I could have made the slow charger work.6. The wheel and sidewalk trimmer. Cool idea I think, just pull shaft collar up, turn shaft around then roll along sidewalk edge cutting grass hanging over the sidewalk. ( No, not made for trench digging like gas edgers :-)7. Line out works as advertised. My string nightmares might be over. The filled cartridge it came with worked like a charm. Line out automatically when needed and no jams. I bought 2 extra refills later. There is an art to refilling your own and my lack of patience in the past has cost me grief.8. Two speed. If you're thinking about it you'll probably will go with high speed, however the other day after finishing one yard I then noticed I had it on low.If your needs and thinking parallel mine somewhat I think you will find this a great buy.
