Can't recommend- shame on Round-up
Three years ago, this product was outstanding. But for the last 2 years, it has only lasted 2 months before weeds come back up. My use and application for all 3 years has been the same. I am super careful to spray all the pebbles on my paths and the block patio and walkways. I can no longer recommend this product as meeting its claims of 365. Best is 2 months.

Great product for DIY landscapers
[This review was collected as part of a promotion.] Works well but make sure you follow directions. Great for thick lawns and start up new sod. Works well in concrete or paver seams in keeping weeds and unwanted grass at bay. Makes sense to block off areas of your lawn without weeds, so that Roundup does not harm healthy grass

Worth the risk
Used it all summer or weeds in cracks if the sidewalk. Sometimes a second application was required. I’ll risk lymphoma rather than go a season without it, with My sloppy neighbors.

Excellent for cracks
I love this stuff!!! I have very large area of asphalt at my house. Because of weather extremes it cracks and it is impractical to have it surfaced every year. Even tho we have no rain here for 5-6 months, it is still a constant battle with weeds. Worst are goat head which puncture tires and dog's feet. Weeds make the cracks worse. I applied this to all the cracks in April, except a small test patch were the weeds are still growing, and at now at almost August. Killed the weeds that had started and NOTHING new. Am now going to try on brick pavers where I fight weeds. Note, we have no rain for 5-6 months so it may make it more effective here. In the past I used regular Roundup to kill the weeds and they were back quickly.

Not Sure About It
[This review was collected as part of a promotion.] This Roundup was interesting because it has the comfort wand and that’s different than what I’ve had before. I did like the comfort wand though! i’m just not sure if it was as effective as I thought it would be. I’m going to keep trying so I can get rid of my weeds and grass that are in my driveway!

Easy to use!
[This review was collected as part of a promotion.] I got this to review and I’ve used per directions, and have yet to see much of a difference. Not sure if I picked the wrong product for my grass. It does bring a lot in the jug, and the spray system is very easy to use! I am just not seeing much difference yet. There are still ants and weeds growing.

Highly Effective on Unruly Weeds & Easy Application!
[This review was collected as part of a promotion.] What is Roundup Dual Action Weed & Grass Killer Plus 12-Month Preventer with Comfort Wand? According to the Roundup Website, the following is an overview of what this product entails. Roundup Dual Action 365 Weed & Grass Killer Plus 12 Month Preventer with Comfort Wand provides one-step weed protection for up to 12 months. This weed control kills and prevents many types of tough weeds and grasses for up to 12 months, including clover, dandelion, large and smooth crabgrass, poison ivy, and other broadleaf weeds, grassy weeds, and brush. It is rainproof in as fast as 30 minutes and produces visible results in hours. Use Roundup Dual Action 365 Weed & Grass Killer Plus 12 Month Preventer where you want to kill existing weeds AND prevent new weeds for up to 1 year, such as cracks and crevices in driveways, sidewalks, walkways, patios, paths, and under decks, gravel areas, and other non-lawn areas. The Comfort Wand® is true to its name. With a one-touch continuous spray, there are no more tired, aching hands! Overall my husband and I had a pleasant experience using this product. We had some weeds that were in the cracks of our driveway, sidewalks, and around our porch. We loved that we didn't have to worry about rain washing it away because it rains a lot during the springtime where we live. The application was easy to apply with the added Comfort Wand and it took little effort to cover larger areas. We both took turns applying the Roundup and it was generally quite easy and comfortable to hold and handle. The results were awesome and this product was highly effective in killing tough weeds! We love the 12-month preventer as it essentially saves time and more money!!! We love that we didn't have to keep reapplying the Roundup to keep the weeds gone! We highly recommend Roundup Dual Action Weed and Grass Killer Plus 12-Month Preventer with Comfort Wand to everyone including friends and family! This product is affordable depending on the size of the yard you have or the overall size of the unwanted weeds! I will purchase this product as needed as it works wonderfully and has several extra features that make it a stand-out product. I received the product for free from Influenster and Roundup in exchange for my honest opinion. Thank you Roundup and Influenster for introducing me to a great product I will use for years to come!

Easy spray and lock feature
[This review was collected as part of a promotion.] Finally got around to spraying the yard. The spray set up was easy to assemble and use. I like the safety lock as my favorite feature. Hoping this is an environmentally friendly and economical weed killer that does its job.

Best weed killer in the market!
[This review was collected as part of a promotion.] I recently tried Roundup Dual Action Weed Killer in my garden, and I'm impressed with the results. This product effectively killed a variety of weeds, including tough ones like dandelions and crabgrass. I like that it comes with a convenient spray wand, making it easy to apply. The dual-action formula not only kills existing weeds but also creates a barrier to prevent new ones from growing. I noticed visible results within a few days, and my garden looks much neater now. Overall, I highly recommend Roundup Dual Action Weed Killer for anyone looking for an effective weed control solution."

Great choice!
[This review was collected as part of a promotion.] This is my go to product for keeping the weeds out of my businesses mulch and parking lot. It prevents any unwanted pop up of crabgrasses and weeds even during the rainy months of the years. It is so easy to hold the container by the top and gentle press the wand to apply. It is easy to hold the wand for those of us with hand issues - no cramping or pain!

Quick to start the weed killing process
[This review was collected as part of a promotion.] Roundup's Dual Action 365 Weed & Grass Killer is easy to use with the spray nozzle and covers a good area. I immediately noticed the weeds start to die after a few hours. However, after one week, the weeds did wilt but weren't completely gone. By the second week, the weeds had shriveled up mostly and had turned a beige/light brown dead color, but some were still present. So it still requires at least some weed pulling at least in my case. Overall, I was still very happy with my results and the ease of using. I will say that if you have a lot of weeds you need to spray, you may need more than one container of Roundup.

Clears out the weeds in between the concrete.
[This review was collected as part of a promotion.] This worked out really well, easy to use, and not too heavy to carry around with me. I only got to use it twice so far, but it killed off the plants growing in my driveway.

Effective and easy to use
[This review was collected as part of a promotion.] So living in a HOA I have to maintain my driveway to be free of weed and grass. Roundup grass and weed killer is very easy to use and effective. The wand works well but be careful not to spray your lawn or plants because it will do its job.

Effective weed killer
[This review was collected as part of a promotion.] Got rid of the weeds we had growing in the cracks of our driveway that were making it look unsightly. The comfort wand made it easy and quick to apply. I don’t love using this with my kids around, though.
