The BEST weed eater one can own.
[This review was collected as part of a promotion.] Excellent weed eater. Easy to use, elements weeds in 1 pass and I get the job finished in half the time. I am highly recommending this product. You wont be dissappointed.

I replaced my my previous trimmed with this same model. I cut and trim more than one lawn a week, so even with more than average hours of use its a good product

Amazing ease of use vs. the gas powered trimmers! Will never go back!

Works just like i expected, the line on the provided spools is very durable!

It was easy to put together to be able to start using it right away. It takes the same battery as my lawn mower and I can do everything I need and still have power left in the battery

Great for weekly yard maintenance
Likes: easy to assemble, matches a 40v greenworks lawn mower so we can share 1 battery. Light/good weight and length for ease of use by 5'1” lady :) Cons: the string ! The string it comes with will go in relatively easily but you have to stop and press a button to have more come through. For small jobs and weekly yard maintenance that is no problem but I am working on taking down years worth of growth . I will be doing that a lot. Don't recommend for big jobs. This is a great tool for a small yard or thinner dry grass. Battery power is great.

MANUAL LINE FEED
It does not have the bump/tap feature to advance the line feed; to have to stop, take battery out then advance line manually and put battery back in… a bit time consuming. I should have read the description better. Otherwise, it's great!!!
