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

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!!!
