                  Worked pretty well, although some weeds are resistant. That is because the company does not use glyphosate, which did a 100% kill of all the weeds. Overall pleased with its effectiveness and ease of use.
                  by
                  Easy to use wand that last quite a while. The product worked quickly and stops the weeds from growing quickly. I’ll definitely plan on buying the weed spray again in the future.
                  by
                  Would give it 5 stars but when removing the wand from the side of the bottle it opened a hole in the side of the bottle and some product leaked out. Taped the hole but still poor packaging engineering. Product worked better then Spectracide at similar price. Don’t get battery operated version stick to cheap manual pump

                  We're sorry to hear that you were disappointed with the Roundup Weed & Grass Killer4 .

                  For the best results spray when air is calm to prevent drift to desirable plants. Spray the weeds or grasses you want to control until thoroughly wet.

                  We value your feedback and are eager to learn more about your experience so we can improve. Please contact us at 877-220-3089 at your convenience. We look forward to hearing from you and working towards a better experience. roundup

                  Don’t waste your money
                  This product does not work at all. I sprayed four gallons of it on my pool pavers and on the driveway. The weeds never died and now have so many more. So disappointed and mad about all the wasted money. Will never buy again. I wish I had my receipts to get a refund.

                    Almost two months ago, my family started to use Roundup Weed and Grass Killer recommended by neighborhoods. After compared with other brands used before, Roundup is the best driveway weed killer for sure.

                    This product kills everything! It is perfect for pesky weeds in our driveway, sidewalks, rock beds and mulch beds. Paired with an HDX sprayer for extra ease in application.

                    It works great, but make sure you spray to the week only because it will kill everything even though it is good grass.
