The product is great, but not the sprayer.
I bought one last spring, along with refill fluid concentrate. When I refilled it, the sprayer would no longer hold pressure, so I went back to the store. They looked it over & replaced it. I finally ran out of fluid again, refilled it, and again, no pressure. The store says they replace a lot of them for just this reason, but it’s been too long since I purchased this one - I have to buy a new one. I’m going to try the Ortho brand instead. So, I’m summary: the weed killer works well, just don’t expect the refillable sprayer to actually be refillable! :(

    We are sorry to hear that you did not get the results that you expected when using Roundup Weed & Grass Killer. Did it rain or was area watered less than 2 hours after application. We recommend that weeds not be cut for two days both before and after the product application to maximize leaf surface and absorption. You can contact us if you would like to continue discussing this or if you want to know about our product guarantee.We can be reached at 866-324-2647. roundup

    Trying to remove any growth occurring between driveway pavers. It's a very large u shaped driveway and I used the entire container in one application. The "u" or lower "h" shaped paved driveway is at least 70 feet in diameter. On the spray setting as opposed to stream, it didn't spray very far or even. I don't think a battery operated sprayer would have done any better. The weeds and overgrowth seems to be turning brown however it's been raining a lot lately. I am concerned the torrential rains two days after application may have weakened the product efficacy. In hand pumping the tank I also had concern of over pressurizing it. However I saw very little correlation of pressure in relation to spray distance. I did manage to cover all the areas I wanted to kill the weeds. A week later I still see some growth in spots. For only $20.00 I made a repeat purchase for a second application. I may purchase a stand alone sprayer and concentrate formula next if this doesn't work.

    Like the convenience
    I bought this and sprayed the weeds and grass I wanted gone and the weeds and grass are still green after 4 days. It did not kill the weeds and grass like it said it would. I am not satisfied at all with this produce. I have used Roundup in life he past and never had a problem like this.

    We are sorry that our Roundup Weed and Grass Killer has not performed as you expected it to. Weeds typically begin to show signs of wilting in one day. You should allow 1 to 2 weeks to completely kill the weeds. If you are interested in discussing the product guarantee that we offer, please contact us at http://tinyurl.com/mx3ua3u.
      Easy to use.
      [This review was collected as part of a promotion.] This is the easiest way to apply. No more sore hands. I apply it around driveway and sidewalks with no overspray or damaging the plants around it. Great design. I will purchase this again when needed.

        Weed Free
        [This review was collected as part of a promotion.] I received this at the start of spring and used it immediately. I go over the landscaping once a week to see where it is needed & as of this week, 5weeks into season, only needed it in 1 spot, really helps to keep the patio clear of weeds

          Easy to use Roundup Weed and Grass Killer
          [This review was collected as part of a promotion.] This Roundup Pump N Go weed and grass killer is well designed product with the pump built into the container. You don't need to connect to a hose or mix in a separate pump. Flip open the spray wand, use the top handle to pump it couple of times and you are ready to spray on any weeds or grass. The pump handle is also used to carry the product around the yard. You can adjust the tip of the spray wand to control the spray pattern. It can be adjusted from wide to a stream pattern. I used this to kill the weeds and small patches of grass growing on the edge of my walkway and flower bed. You don't have to spray a lot. Just a quick spray to coat the surface will do. Give it couple of days and you will see it yellow. Eventually it will wither, dry, and die. The product works well.
