Review: Sturdy, saves time and money. - Great for an average yard , home, business etc. It’s light but not flimsy. Easy to trim around. patio, landscape etc. The autofeed string works well and not wasteful. The battery provides more than enough power and time . I have 4 of the batteries and a charger. I also use them on the other Black and Decker stuff I have. Sander and reciprocating saw. No gas, no cords .Sturdy and saves time and money.
Review: Weed eat away - This is actually a replacement purchase because I was not being careful and fell on the other one and bent the shaft to the point of destruction. Quality, price, functionality, purpose are all excellent. Loading new spools is quite simple. If there is one drawback i would have to say the orange cover for the spool can wear out rather quickly if working around a lot of concrete. Very easy to maneuver and light weight. Has plenty of power for the 2.0 amp battery. Once i have the yard trained I can weed eat the front and backyard on one charge. In fairness my yard is slightly below normal size. Very easy to assemble. I also have the mower attachment that my wife really likes.

## Questions & Answers

**Q: If you ran it wide open, how long will it run until a recharge is needed?**
A: About 15 minutes max. And do not recharge it while the battery is hot.

**Q: Is this trimmer very heavy...I am 5 ft. tall and cannot handle trimmers that are for people who are taller, and if it is overly heavy.**
A: The length of the trimmer is adjustable and is not heavy.

**Q: Does this come with line string to start you off or do you need to purchase this separately?**
A: It comes with minimal string - I'd say maybe 3 ft. on the spool.  There's a pack of three on Amazon - a generic brand - for @$10.  Just get those when you order.

**Q: Does the LST300 come with batery and charger?**
A: yes it does come with both...handy little tool, light weight & does a great job. the batteries don't last long, but my fence row has grown tremendously because my other died, but still great tool. takes app. 4 hrs to completely recharge. I also boutght an extra charger + battery. helps a lot.

### ⭐⭐⭐⭐ Good for light & med duty maintenance
*by K***R on July 6, 2025*

I’m on my 2nd one of these and it’s on the fritz now. 1st one lasted about 2 seasons. This one is about to go out after 2nd season. Why keep buying? Because I have bought 8 batteries and several spools of string spools. I have a big yard with a lot of trimming. So basically an average yard would probably get 4 - 6 yrs use. My property however is pretty big. Takes 4 - 5 hours just to trim. As long as you keep it trimmed, this thing does a good job and is light weight. If u let jt go for 2-4 weeks, may as well get the gas trimmer out. This weed trimmer is good for moderate to light duty grass. It’s not powerful enough to get anything long or thick. So you hafta stay on top of trimming. If you do that, this will be an effective alternative to a heavy gas trimmer when you have plenty of time to trim. This thing is slower than a gas unit because it’s low power. I will buy 1 more of these but as my batteries start to wear out, I’mma start tossing them and not replacing them anymore and switch to a 40v. I’m ordering another one at $76 only because I have 6 good batteries and just ordered 2 more before my trimmer started acting up again (Early stages of the motor going out). Like I said, for what I put it through, can’t really complain so I’m giving it 4 stars.
