Quick Switch Refill
[This review was collected as part of a promotion.] This is a quick and easy refill that simply needs the sprayer switched over from the original bottle. The original bottle is very long lasting that I have not even needed this backup product yet after treating my driveway and sidewalk.

Helpful for small areas
[This review was collected as part of a promotion.] This is a great product for small areas. Personally the weeds that come up from cement cracks in my pool cage is my mist pesky and bothersome weed. This type of spray is perfect sizing to take care of there without a professional. It’s safe and easy it takes time to get rid of the weeds and this product will never keep them away forever but it’s a good easy solution if you use it as needed and as directed. I used this in areas that are more s...

Good stuff!

Good to have!
[This review was collected as part of a promotion.] I used this product on unsightly grass in the back yard. It was easy to spray, which is sometimes difficult for me do to arthritis in my knuckles. It took a couple of day’s, but no more grass!

Doesn't kill weeds
[This review was collected as part of a promotion.] This unfortunately doesn't seem to kill weeds. I used a whole bottle 2 days ago and the weeds were still standing tall so I busted out the refill and did another whole bottle and the weeds are not dying. I love the QuickHand sprayer, but why should I have 2 whole bottles not kill some very average weeds?!

QuickHand is awesome, but no weeds have died
[This review was collected as part of a promotion.] This QuickHand design is the best thing to happen to weed killer since its conception, unfortunately the product itself hasn't had an effect on any type of weed I have tried it on. It's been 2 days and the weeds look the same. This is not for lack of weed killer, I have gone through an entire bottle on a very small area, no rain, just no effect whatsoever. It's a shame because I have fallen in love with the way it sprays. It's actually really f...

Affordable
[This review was collected as part of a promotion.] The Roundup Dual Action Weed & Grass Killer Plus 4-Month Preventer Refill is a great value and just as effective as the original bottle. It refills easily with no mess and saves money compared to buying a whole new sprayer each time.

Great results
[This review was collected as part of a promotion.] I’ve had really good results with Roundup Dual Action Weed & Grass Killer Plus 4-Month Preventer. It does exactly what it promises—kills existing weeds and helps prevent new ones from popping up for months. I noticed visible results within a few days, and the treated areas stayed mostly weed-free much longer than with regular weed killers. The application is easy and convenient. My only reason for giving it 4 stars instead of 5 is that it work...

Gardener must haves..
[This review was collected as part of a promotion.] Can we take a second for this handle!! It’s amazing, especially for people who may be old or have health issues with their hands etc. Ready to use this already as I know that the yard work will be wild this year. I believe this one will work on at least half of my yard if not all of it.
From roundup.com
Must have!!
[This review was collected as part of a promotion.] Having a refill on product is seriously amazing!! I personally will purchase products more if they come with refills. I’ve used this brand before & it’s always been good. I know that this year that the yard work will be hard as we have had rain & snow so far.

Awesome works well
[This review was collected as part of a promotion.] I unfortunately didn’t have a photo before. I got to use this, but I will say it works almost instantly. I have a small backyard, thankfully, but I spray in between all the rocks and within a few days I can notice a big difference. I barely have any weeds growing anywhere? It’s truly a lifesaver. Works so well.
