## Customer Reviews

### ⭐⭐⭐⭐⭐ This gray jug works, the white ones are weaker and the sprayers don't work.
*by  on Reviewed in the United States May 10, 2026*

This one is the real deal! I got tired of wasting my money and time on the white jug of round up only to have to go back and spray weeds again, not to mention the really poor excuse of the sprayers ! I've had to transfer the liquid to my garden sprayer to use the product. This has happened the last 3 or 4 times I have purchased it. This time I finally got a positive experience. It was more expensive but actually saved time and money because it actually works as advertised !

### ⭐⭐⭐⭐⭐ Worth the $
*by  on Reviewed in the United States June 18, 2026*

Worth the money! I used this on our patio and in some of our landscaping where there are large gaps that were allowing SO. MANY. WEEDS. to come through. Also used on our dirt driveway in some spots. Weeds completely died within a couple of days and none have come back. We just got a lot of rain, so I am curious to see if this lasts as long as they claim it should. Will update this review if they lied 😂

### ⭐⭐⭐⭐⭐ IT WORKS-so far
*by  on Reviewed in the United States June 9, 2026*

Follow the instructions cuz it’s easy to use. It beats spending all your time weed pulling. I spray it on, wait a couple of days and rake up the dried detritus. Price is good cuz it really does work
