I most definitely buy it again.
[This review was collected as part of a promotion.] Im an avid gardner so I used this product, and the idea of a concentrated weed killer is great for me. If you have limited space for all your gardening equipment the small bottle most definitely work. The product itself is as good as the original if you can follow the steps to mix it with the right amount of water, and off course you are going to need your own sprayer. My only suggestion is to have a measuring table in the cup, since this is sort of toxic liquid, having a measuring table in the cup would allow for a better and more efficient mixing, at least so that we can measure how many cups per gallon of water.

Works quickly
[This review was collected as part of a promotion.] We live in the country and our driveway easily gets weeds in the cracks. This Roundup works quickly and is easy to use. Within days the weeds are dying. We feel safe using it around our kids and animals. A little bit goes a long way. I recommend.

Easy Application, Effective for most things!
[This review was collected as part of a promotion.] Application was easy with the sprayer I already had. Was very effective on grass and most weeds, just not the invasive ivy I have where I am located. Great if you want to kill just grass and non invasive weeds!

Work Fast!
[This review was collected as part of a promotion.] I’ve used a lot of weed killers, but Roundup Weed, Grass Killer Concentrate really does the job. It works fast — I mixed just 6oz with a gallon of water. I sprayed in the morning and could already see the weeds curling up by the afternoon. By the next day, they were dead. If you want something that kills quick and doesn’t waste your time, this works.

Works
[This review was collected as part of a promotion.] Roundup helps kill the weeds on our fence line so it’s easier to care for our lawn. The price for this container is a good value allowing multiple uses. Roundup kills what we spray it on but doesn’t spread out to areas that we didn’t spray so it doesn’t harm our other plants or grass.

Great refill for weed control
[This review was collected as part of a promotion.] Roundup Weed killer has been a staple of my yard maintenance. It does such a great job at leaving the grass but making weeds go away fast! I like to spray it on weed in my driveway as well. This product is great because it refills your existing container by mixing with water-so this small container makes gallons!

Would prefer ready to use
[This review was collected as part of a promotion.] Not a fan of having to mix it—definitely prefer something ready-to-use. It’s too early to tell if it’s doing the job, so I’ll have to wait and see on effectiveness. Hoping for good results, but the prep is a bit of a hassle.
