Review: Good value for the price - Among the Bargain price trimmers, it's hard to ask for more than this one gives. Easy to use, the line rarely fouls, and it's easy to untangle. Light weight, mobile, cordless, reliable, strong- for a small back yard with an operator that is only in the yard because he has to be, this unit is great- especially for the price. I chop a 30'X13' yard of 6" high thick mixed weeds to ground level in 15-20 minutes with this and I still have charge in the battery.
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.

### ⭐⭐⭐⭐ Not the most durable but my first choice
*by J***R on February 11, 2026*

Pros Works well – It works well and starts without failure every time. Start time is immediate. Weeds will start trying to hide under the grass when they see you coming with this. Quality – The quality is good and solid. It’s typical of the usual Black and Decker products I’ve owned. Battery Life – The battery life is strong. I use this across several properties and have never had to switch the battery out. Weight – The weight is light and easy to pick up. It feels about the same as a rake or a typical garden tool. Ease of Use – The trimmer has no vibration and is easy to control. Switching the line when it goes out is quick—just keep the line tight and thread it through the hole. Power – Like all Black and Decker tools, the power and speed is great and it gets the job done. About 70% of my tools are Black and Decker, and this is one of the main reasons why. Value for the Money – Black and Decker is one of the cheapest product lines and worth every penny. I appreciate the pricing. Cons Durability – This is the only con, but not a deal breaker. When I put my Black and Decker tools back in the truck, I NEVER throw them in—I PLACE them in. There is a difference.
