The variable speed control and automatic line feed are noted as helpful features. Users appreciate the lightweight and cordless design, finding it comfortable and convenient to use. However, some customers have experienced issues with the trimmer head dispensing too much line or the motor seizing up after limited use. Battery life may also be a concern for larger properties.

7500 sqaure foot + edge and no dead battery!

Would Recommend

I have been using $30 corded B&D trimmers for about 6 years before I finally woke up to the cordless world. Didn't want to try the gas route so picked this up for $150.00 before the sale ended. With a 3.5 dial setting I was able to weed eat for a straight 15-20 minutes and also edge about 100 yards of sidewalk. The battery still had about 25% of it's power left! Was contemplating purchasing a spare battery but apparently one battery does the job. I didn't care much for the safety you have to pu...

Plenty of power!

Would Recommend

This trimmer has plenty of power to handle waist high weeds and grass. The battery lasts around 30 minutes going nonstop on level 1 power. No gas to buy, less noise, no fumes! I was so impressed with this trimmer I bought a second one for my husband - now we can both work at the same time!

Skeptical at first but now a believer

Would Recommend

I only purchased this product because of the many glowing reviews and the fact that it said on the box that I could try it for 30 days and if not satisfied I could return it. I did not return it after 30 days and I am very happy with the purchase. I read a few reviews complaining about battery life. The biggest factor in determining battery life is in the power setting. I run mine almost exclusively on 1 and it still has half a charge left by the time I finish my usual weed-eating routine. If yo...

This weed-eater ROCKS!

Would Recommend

I had an older cordless Black and Decker from about 5 years ago and it had very little power and I have always had to jack with the line - every time. So when a friend recommended this B&D I told him no-way am I buying another Black and Decker. But he explained how POWERFUL it was, how the line is ALWAYS and AUTOMATICALLY feeding out so there is no tapping, pulling or having to stop and turn the thing over and mess with the line - so I bought one - and he was right. This thing is the ticket to t...

Well Satisfied!

Would Recommend

This Black & Decker LST 136 performs as advertised. If you expect it to mow the south 40 that you should have had your local farmer bail for hay, then this is not your tool. If you have an acre or less lawn with numerous trees, planting beds and sidewalks this is your product. I purchased a 2nd battery and was able to accomplish all trimming on those fully charged units. Use the lowest power setting that you can(It will do fine on 1 or 2). No gas to fool with and no pulling and pulling on starte...

Works great

Would Recommend

I bought my trimmer a year ago and I am really glad I got it. It works great. It has a long battery life and as much power as gas string trimmers I have used. 2 cycle gas trimmers are notoriously hard to start and there is the hassle of buying gas and oil for them. I like the 36 volt battery better. It is quiet and no starting problems. I highly recommend this trimmer.

Good string trimmer - Not so good edger

Would Recommend

The first one of these I bought was defective. The plastic guard was damaged. So far this trimmer seems to work good at trimming. I'm not impressed with the edging it does but I may just need more practice. The battery didn't last long enough and I only have a few areas to do.

Perfect for me

Would Recommend

I never thought I'd use a cordless trimmer. I have a large piece of land with a lot of landscaping, trees, stone, etc. I had recently purchased a new gas trimmer, a 4 cycle, 30 cc beast that really got the job done -- sort of. I have only minimal use of my right arm and after two neck surgeries, it isn't going to improve. I can't even finish 1/4 of the yard with that heavy thing. Well, this cordless trimmer does just as good a job and I can finish the whole yard on 2 charges. That's fine. I don'...

Doesn't hold charge

Would Not Recommend

This trimmer has a really great design, easy to change the trimmer string, and light weight. The rub is that it will not hold a charge. I set mine on 3/4 range for a medium power output while trimming. It took me 3 to 4 hours of extra time to edge my lawn, I had to stop and recharge about every 30 min.

poor battery time

Would Not Recommend

You would think a 36V battery would give you more then 30 minutes of cutting time, Cutting med. high grass on the 4 setting. It works great, but you will need a second battery. It would be nice if you could get a discount on a replacement. battery

better than expected

Would Recommend

This is an awesome machine and it works very well for trimming tall grass and weeds around the lawn and garden. This is different from a 2 cycle gas trimmer in that it does not have the same brute power but it compensates by using a high speed and low drag because the motor directly drives the cutter head. It is also much lighter and better balanced than a gas trimmer. I was skeptical at first but so sick of mixing gas, hard starting, NO starting, and constantly clearing line snarls that i had t...

Hassle free..at last

Would Recommend

I have struggled over the years with dragging around 100' cords and gas powered triimmers that wouldn't start. I have a relatively small area to trim (15 minutes) and decided to go cordless/gasless. What a difference. Grab it, flip the switch, pull the trigger and go. I hate yard work, but this makes it almost enjoyable. I wish I had bought this trimmer sooner and saved myself a lot of frustration.

Good but I took it back

Would Recommend

So I wanted to like this, wanted no cord and no gas, and it does work well, just the battery doesn't last long enough to do what I need. Were on a corner lot, lots of sidewalk and fence, lot's of stuff growing this spring, made it about 1/4 - 1/3 of what I needed on one charge, takes over an hour to charge, so this is going to take awhile. I took it back and bought a $240 4 stroke Troy Built, we'll see how that works out. All in all this is a decent tool, a bit more plastic and cheapish feel th...

Works just as I had hoped

Would Recommend

I was glad to find a 36V battery trimmer/edger to keep the woods next to my home at bay. It removed most of the brush but occasionally got tangled in the vines. A bonus is the 6 power settings! Pretty powerful for battery operated.

Exceptionall Poor Performance

Would Not Recommend

I have a large property and struggled with the decision to either purchase a gasoline or battery operated string trimmer. I was sucked in by the 36 v lithium battery of this unit. I should have known it was a bad decision at the time of purchase as I went to purchase a spare battery only to find that the spare would cost almost $90. Unfortunately I discovered that the lithium battery lasts less 10-15 minutes of usage before requiring recharge. I appear to have purchased a moderately expensive el...
