BLACK+DECKER 20V MAX 12 Inch Weed Eater Cordless String Trimmer and Wheeled Edger Lawn Tool with Spool, 2.5Ah Battery and Charger Included, Lightweight, 2 Speed PowerDrive (LST522)

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 also 5. 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.

Love this for small jobs and the batteries last.

The unit itself is very nice. Seems sturdily built and is lightweight. Adjustable length works well and locks securely. I question the need for two speed control, but their claim is the lower speed saves battery power. I am not sure how much of a difference it makes and changing speeds in use is not very intuitive. A better choice would be an in between speed which is permanent to get better cutting and a little longer battery life. My annoyance comes from the lack of much information about the "automatic line feed" and how it operates. The fact is, the user's manual is bare bones for user information. The booklet is small, is divided into three languages, and all of the "icon" diagrams to explain things are so small you need a magnifying glass. I wanted to know what triggers the line feed, how it knows to lengthen it, and how it knows to stop feeding. None of that information is in the book or on the Black and Decker website videos. Aside from that, the unit is built well and should be durable. It is a good value for the money.

I’m very well designed trimmer that cuts through grass and weeds very easily. The battery lasts about 45 minutes. It’s fairly light and easy to use. I think it’s also a pretty good value.

Easy to use, effective

This was a gift for my husband’s 77th birthday. He loves it. He has already used it several times. He says it’s the best cordless trimmer he has ever owned.

This is my second one. Light weight and easy for me (old woman) to handle. Unit rotates so you can edge. The old one lasted right at 6 years. My old batteries work on new unit also. I get the one with the wheel which makes it much easier to edge. This one auto feeds and my old one didn’t. I don’t know how I feel about the auto feed. Another brand I had before with auto feed stopped working. That was a pain to manually feed. Have only used the new one twice

This is my second black and decker weed eater. Very disappointed. The first is at least 10 years old and was more powerful. The only reason I replaced it was because it stopped feeding. The BD people told me they didn’t make parts for it anymore. I’ll not buy another. Not as powerful and the battery lasts maybe 15 minutes.
