Quality product
Repeat purchaser for this product. It works wonders killing weeds. Good coverage without the bulk. I have a sprayer which I purchased from Walmart. I get more value for the money than buying ready made product. I see less weeds returning each year using this weed killer.

Fair priced Product that worked as stated on the k
I have an over abundance of stinging nettle and this product is working well to kill this invasive plant. So far, I've sprayed at least once and some a second time after 2 weeks. Stinging nettle is a tough plant to kill, so I fully expected at least 3 spraying. It will not kill you grass! It does not kill quack grass. So don't be worried about spraying this on your lawn for dandelions, etc.

Way Better than Brand X
This was the first time I used this brand of weed killer. It worked far better than the previous brand I was using. Saw results within a couple of days.
