Customer Reviews

Weed & Grass Killer III with Pump 'N Go Ready-To-Use 2.1 Sprayer is rated 3.8 out of 5 by 175.
Rated 4 out of 5 by from Product is wonderful! Sprayer, not so much... The only reason I am not giving this a 5-star is because of the faulty Comfort grip Sprayer Wand. It stopped spraying 1/2 way through. Had to pour the product into my manual sprayer. I live in the Tampa Bay area. Sprayed on the weeds at 11:00am. It began to rain at 3:30pm and I was upset. At 4:30 when the rain stopped I went and looked and the weeds are already dying!! I have used a few other brands of grass and weed killer and #1- The rain would have effected it and #2- It takes about 4-5 DAYS before I see results! Great product- just use your own sprayer tank.

Rated 1 out of 5 by from Weak Spray and Low-Quality Pump (Flimsy Gasket) The spray is fairly weak. Plus, when I refilled the container, I couldn't get a spray (the pump didn't pressurize the container). I found that the casket which seals the pump to the container's mouth is very flimsy. As you tighten down to ensure a good seal, the flimsy gasket is easily deformed, thus no sealing is achieved. I had to use a dull knife to unkink the gasket, which was twisted. I recommend that a small amount of lubricant be applied to the gasket before attaching the pump unit to the container's mouth lip. But, for all that trouble, I'll just instead buy Round-Up concentrate and use my Home Depot $10.00 generic 1 gallon pump sprayer, which is a better sprayer than the Round-Up sprayer. Regarding weak spray, I know that spray has too be not powerful so that dumb people don't spray everything within 5 feet!, but come on guys the spray of this product is so weak that it takes a long time to get a job done.

It is a Killer of anything growing that you want to get rid of without pulling or if you pull a weed and want to kill the root. I have used this for years and love the way it works and helps me,

Rated 5 out of 5 by from Truly Amazing Customer Service I had recently written a review about the Round-UP Ready-to-Use Pump 'N' Go Weed And Grass Killer in which I mentioned that the basic idea was great, but the sprayer had stopped working half way through the container. I didn't even give any thought to contacting the manufacturer about my problem so I was AMAZED that I received an E-Mail from Scotts Miracle-Gro who makes this product. They not only apologized for the problem that I had, but they sent me a refund check for the price paid. Who does that??!!! That is great customer service, and I can assure you that I will not only continue to purchase Round-UP, but I will also buy other Scotts products like Turf Builder Lawn Fertilizer, and Miracle-Gro Plant Food. A special thank you to Karen Rausch of Scotts Company who followed through on this. Really great work Karen!!!

Rated 1 out of 5 by from Sprayer not working Purchased 2 of these PumpNGo sprayers and can't get more that a stream for about a second then nothing but drips...tried pumping more and the same thing.....fiddled with the cap and still nothing. Can't really recommend a product that I can't get on the weeds. I've used all kinds of sprayers in the past, don't understand what's up with these.

Rated 3 out of 5 by from Pump and Go sprayer not working The product does kill weeds, but the pump and go sprayer seems to be garbage. I used it once, stored it as per directions and CANNOT get it to work again. I paid a fair amount of $ for this product, expect to be able to use it.

Rated 1 out of 5 by from Pump N Go 2 sprays as poorly as Pump N Go 1 I know the product works to kill weeds as I have used the small bottle with great results. However, I can't begin to describe my frustration with the large container with the pump n go sprayer. I bought one with the pump n go 1 last year and it is still in my garage 90% full, because I don't have time to wait for the fluid to dribble out the nozzle. Last week I was thrilled to see the same product with a 2 after it and thought, Great! this year my landscape will not look like my armpits. Well wouldn't you know it, the exact same very poor application performance - EXACTLY! I am a patient man and keen for a good challenge with a good mechanical engineering background, but please help me to understand how this design gets thru the quality control dept.

Rated 5 out of 5 by from Custer's Last Stand for Weeds! I saw all the commercials on TV for Roundup and I was a little skeptical at first but decided to give it a try anyway. Glad I did. It clears up weed or grass growing from concrete cracks but I especially like the way it works on hurricane fences. You don't always get all the grass growing by the fence with a grass trimmer, so I started spraying this around the perimeter of the fence and it made it easier to use the trimmer next time. Also works great around my above ground pool. I don't want to puncture the pool so this kills the weeds and grass so I can use the lawnmower around the pool. I am a Home Depot associates and I recommend this product to the customers.
