Does what it claims to do.
[This review was collected as part of a promotion.] Set up was a breeze. A few pumps went a long way when spraying down my driveway. Handle kept me far away from the liquid. Sprayed it down on a cloudy day. Next few days were hot and it did the job. Weeds are drying up. Great product

Great weed killer!
[This review was collected as part of a promotion.] This roundup works excellent. I used it for the weeds along my driveway. We sprayed them in the evening and by the next morning they were brown and shriveled. We’ll see if it lasts the full 4 months. So far so good!

Overall good!
[This review was collected as part of a promotion.] This weed killer got rid of those stubborn weeds! It worked wonderfully because it looks like it won’t grow back. It is safe to use but I usually avoid the area.

Actually works
[This review was collected as part of a promotion.] The grass killer is very effective. I was really excited to test it out with weed access on my lawn and it worked like a charm. After just one use I can already see the difference. The container comes in a good size and would last for a while.

BEST weed killer!
[This review was collected as part of a promotion.] The BEST weed cleaner, hands down, that I have ever used. I had overgrown weeds creeping through my concrete and in less than 24 hours, they were dead. See the photo! I will definitely repurchase! I would caution to wear a mask and gloves as a precaution when using, since the efficacy is so immediate. I cannot imagine it’s good for the lungs.

Would try other products
[This review was collected as part of a promotion.] After using round up. There is a strong smell so don’t use near kids. The product didn’t work so well in some areas. Packaging is nice and simple and I feel like there may be better products out there for same money.

Works great and fast!
[This review was collected as part of a promotion.] I'm super impressed with the Round Up Weed and Grass killer. I sprayed this on some weeds and within 2 days they were dead. Easy to use and one jug will cover large areas if needed. Like that it lasts up to 4 months!

Visible results may take several hours. Use only i
[This review was collected as part of a promotion.] The round up dual action weed & grass was pretty effective in killing off most of my weeds that I sprayed it on. I like that it has a pump. After pumping up the bottle, the spray stream lasted a good while before having to repump the bottle. . Time will say if the 4month prevention will work.

Weed killer is weed killer
[This review was collected as part of a promotion.] Weed killer works great but regrowth happened pretty fast so not real effective for a long period of time. This pump function is very convenient so you don't have to mix anything.

Weed and grass killer

Works extremely fast and is super effective!
[This review was collected as part of a promotion.] I’ve tried several weed killers over the years, but Roundup is by far the most effective. Within just a few hours of spraying, I noticed the weeds starting to wilt, and by the next day, they were completely brown and dying off. It works exactly as advertised and saves me so much time and effort in maintaining a clean yard. I especially appreciate the precision spray wand, which helps me target weeds without affecting nearby plants. If you’re lo...

My trusted brand
[This review was collected as part of a promotion.] Arrived just in time when I need to buy a new bottle. The result started showing in a few hours and by 24-36 hours the weed and grass turned yellow. The spray bottle is very easy to use and carry around. Not a pet-friendly option but other than that, I’m happy with the result. Now we’ll see if it’s able to prevent weed from growing for 4 months.
