Black & Decker LST400 12-Inch Lithium High Performance Trimmer and Edger, 20-volt

This Review is for the Black and Decker LST400... Originally purchased back in September of 2014.BLACK+DECKER LST400 12-Inch Lithium High Performance Trimmer and Edger, 20-voltI rarely (if ever) take the time to write reviews, but I feel the need to say something after ~2.5 years using this wonderful little trimmer. It has become my best friend over that time. I live on a 1 acre lot at the edge of a forest and am constantly beating back nature with a push mower, a pole saw and this lightweight workhorse. I know that the world of battery powered trimmers was a desolate wasteland for many years. The batteries were permanently enclosed, the size of small vehicles and weighed about the same, causing painful backaches and severe cases of "noodle-arm" upon completion of a trimming session. I know this from experience... I have one sitting in my garage waiting to be recycled. Add to that the fact that said battery would discharge and die long before I was even close to being done with the job and you have one heavy, noodle inducing pain in the butt.I purchased the B+D trimmer over 2.5 years ago along with the replacement spools listed below and have been loving it ever since.Replacement Spools:BLACK+DECKER AF-100-3ZP 30ft 0.065" Line String Trimmer Replacement Spool, 3-Pack1. Battery: This battery is awesome. I have kept it plugged in and sitting in the garage since my purchase with no problems. It is small, light, easily installed with a click and powerful. I have never had it run out on me. Now... I don't go try to clear heavy brush with this trimmer... I trim weeds and grass with it. I might run this thing for about 30-40 minutes after I am done mowing. It runs longer than I do after a day in the yard with an old, but trusty push mower.2. Weight: This thing is LIGHT. Now... granted, I am comparing it to an old Toro battery powered trimmer that might actually contain a car battery, but I also have a gas powered trimmer that is 2-3 times heavier than the B+D. I am easily able to carry this around the yard, even after spending 2 hours pushing a mower up and down the hill on which I live.3. Adjustable/Size: Some of these trimmers are made for people who are 4 feet tall. Not that there is anything wrong with that, but one would think that a 5'11" man would be considered a pretty easy fit for such equipment. This unit does a good job with adjustment options to make sure one is NOT bending over catching weeds in the face while also ruining his back.4. String durability/Spool replacement: I bought 3 replacement spools of trimmer line at the time I made my first purchase and still haven't used them all. Replacing them is easy... no more fighting with the business end of a trimmer for 10 minutes only to find out you didn't spool the line correctly. One should simply not have to stare down the barrel of one of these things longer than you are actually pulling the trigger.5. Durability: While I know many will say that 2.5 years is not that long and that my expectations are a bit low to be happy with performance out this far. Well... in this day and age of planned obsolescence and disposable products, I have learned to be impressed with a power tool that does what it is supposed to without snapping in half or frying itself in less than a year. Just sayin'.All in all, I love this thing. Hope the review helps.

So far it is awsome! Been using it about a month now, at least once or twice a week. The battery has kept up for the intervals I've used it. It has great power on the #2 setting for larger weeds. Although it has a tough time knocking down weeds w/a trunk the size of a Sharpie marker or bigger. So don't expect too much. It is super for my uses and light weight. I can actually balance it on one finger with the battery in place. That was one of my main concerns was the weight. When using a gas trimmer, my arms wear out cause they are too heavy. Also love the fact that I dont have to pull start it.My mate didn't want me to buy it-but he is now glad I did-cause I help more with our big yard!Actually, loved it so much, I showed it to my sister and she bought one too! Hope she loves it as much as I do!

One battery never would hold a charge. The product I ordered was replaced by this "new and better model'. Not half the product my old one of several years was. This one is fragile at best and now after 4 months will not work at all.

This is a battery operated trimmer, so I did not expect a lot. However I just finished my relatively small front yard approximately 800 square feet and it completed everything with one battery charge! Not too shabby I'd say. The power was enough to mow the grass and trim the edges. The tough grass roots were a challenge, mostly because of the plastic line of course, but you can always pull those stubborn ones out by hand. I am more than pleased with this product and now all I need to do is buy the rapid charger to be able to rest and do the back yard in good for lunch next time. If you need a trimmer that is light, easy to assemble, do not want to fuss with a gas start system or an electric cord trailing behind you and quickly be able to do small jobs, then this is THE trimmer for you as well. I can not comment on battery life over time as this is my first use. I will post back in like 6 months maybe sooner. If you need it, buy it because it works and works well.

I've only used this twice so far, but I am really liking it. Not having to deal with a wire makes it SO MUCH EASIER to get myself to do yard work. I don't have to carry around a wire, always worrying that I'll get it in the way and accidentally cut it. I don't have to unwind the cord and then wind it back up again afterwards. To me, the most frustrating part of having to use a wire is when I think I'm finished and wind up the cord, but then realize I missed a spot all the way on the other end of the yard. Now, I can just walk back and get the spot I missed! It's amazing.I'm still getting the hang of the whole edging thing, but trimming and weeding is very easy. The battery seems to last more than long enough. I didn't time myself, but the first time I had a LOT of weeds to get rid of so it must have taken more than half an hour at the least. I only had to switch it to the higher setting for a minute or two for some thicker weeds, the rest of the time the lower setting was more than adequate for my yard.It's pretty light-weight.. I'm not that strong and I have a lot of back and shoulder problems, but this trimmer didn't cause me an excessive amount of pain. It is able to be adjusted very easily, including converting from trimmer to edger and back. I don't think it's any heavier than the corded electric one that I'd been using before this. It is a LOT lighter than the old gas one that I used to have, which I never used because it was too heavy (and difficult to start). This one seems just as powerful as the electric one I used to use.I'll have to wait and see how the battery holds up throughout the season, but so far I'm very happy with this trimmer.

Es un buen producto, cumple con las expectativas, llego antes de lo estipulado

Was just what I needed,easy to use! Plenty of power! I have a big lot and it takes care of all the trimming...battery has plenty of juice..Very pleased with fast shipping and price.

I continue to have good experiences with Amazon. Rec'd this item in only 4 days in the original packaging. Only took a few minutes to put it together and charged up the battery for 10 hours. Already used it a couple times for 15 minutes each time and it works as expected. No surprises. I can put my electric unit and extension cord away now. Was thinking of buying a gas model, but glad I decided to try this model with battery.So far, I like everything about this unit. It's lightweight, quiet, has enough power, has a full length switch that is easy to grip. The auto feed spool works great and is easy to change. I will order the replacement spools from Amazon when I need them. The grass trimmer and replacement spools are cheaper on Amazon.An added bonus. I am planning to buy a B & D cordless drill and the battery from this grass trimmer will fit the drill I plan to buy. Would recommend this grass trimmer.

Unfortunate because it was great otherwise. I think the part is $3 to fix this, but hard to find.

This is simply the best string trimmer and edger I have owned. It's lightweight and well-balanced. The simple addition of a wheel over the cutting side ensure that I don't get too close to walls, fences, etc. to inflict unintended damage with the trimmer. It enables the trimmer to maintain a constant distance from walls to provide a perfect clean finish after mowing. Plus, the head rotates to make a perfect edger with the weight of the unit resting on the wheel, enabling a constant continuous trim along driveways and sidewalks. The lithium-ion battery pack is usable across a wide range of Black & Decker power tools, so if you buy one of them you have a back-up battery for bigger jobs.
