Review: Good Product - Good product. Workes well and the battery stays charged for quite some time so you can get most of the job done. Light weight and easy to handle.
Review: light weight and no assembling needed ! - First of all, I'm not a handywoman at all. I was spoiled to have others /guys did it for me. Under the current circumstances, I have left with a DIY option or wait till all the weeds are 2 feet high. I was nervous to buy lawn equipment online and to use it the first time. After spending more time research than waiting for the delivery, I finally got it three days ago on desertcart prime. Today I was brave enough to open the box and pleasantly found that it is not only super light but also well-built and needs no tools for assembling it. ok, you only need a screwdriver to take the only screw out and put it back when connecting to the main part of the equipment. after charging the battery for about 4-5 hours. I went out to test it. Wow, I am so excited by how easy and effortless this trimmer operates. After spending a good half an hour cleaning up front and backyards weeds, and flower beds, the battery is still working fine. I’m very happy and pleased with the first lawn equipment I own and use it without tears or frustration. Ladies, be brave and try this one, you will like it. now you know why guys call their tools toys. I enjoy using it and the result is amazing too. who does not like a fresh-cut and weed-free lawn?

## 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.

### ⭐⭐⭐ Nice and light little tool
*by K***R on 21 March 2017*

Nice and light little tool. Takes 5 hours to charge the battery and one the first charge it only lasted 20 mins. Second charge just over 30. Hoping it will increase a bit more. Buy a replacement nylon when you order as the one with the product is super short. Oh and this is imported from the US so you need a step-down converter as well. Kind of working out expensive!
