Great product

[This review was collected as part of a promotion.] This weed and grass killer is great. Don't use it if you don't want to kill your grass in a certain area

48 hours later and everthing sprayed is still alive and well

Title says everything. Didn't even kill a small patch of grass in a crack in the driveway. Does not work

Waste of money.

Works no better than the regular formula. I have a gravel area between my lawn and sea wall. I'll spray the entire area, works to kill existing weeds but does nothing to prevent new weeds, and yes I mixed it per roundups specs. I even increased the concentration level once hoping for better results. Within 3 - 4 weeks I have to spray again. Cost double of the regular formula and same results. The label says control for "UP TO 4 MONTHS". Needs to be changed to "WEEKS". My bad for purchasing more ...

maybe just EXTREMELY slow

applied according to directions with a brand new sprayer and after 3 days have a yard full of happy, healthy weeds. Maybe it's just really, really slow-acting. Not even concerned about the extended-control part as there's really no way to guarantee that a 'film barrier' on a driveway will remain unbroken. Weather is hot and humid yet only a very few of the weeds are even beginning to curl very, very slightly. Have had better luck with regular Roundup but even that takes a while and multiple uses...

Great for gravel pathways and driveways

I purchased this early last spring (2016) in the concentrate form. After reading some of the comments before purchasing, I knew ahead of time that it works best by taking a bit more time when applying. The stones need to be wet to seep into the ground. I did the pad where I park my car that was filled with weeds. I normally spray it a couple times a year with regular Roundup. Here it is, almost a year later, and there hasn't been one weed to be seen in almost a year! You may have to pay more for...

Work for almost 2 months

I sprayed around my pool on May 9th; it worked great killed all the weeds. But about a month and 1/2 later the weeds were back.

Did not work!

Applied to weeds around trees and other spots in my back yard in early September. it was 85 degrees at least. No rain in weeks. Live in mississipi. I followed directions and nothing after one week! So sprayed again and still nothing! Did not even kill grassy weeds around a stump. Didn't kill ivy or other lil weeds that pop up. I must have got a bad batch or something. I noticed nothing besides a couple of brown leaves that quickly greened back up.

works good but

this product does a good job of killing and preventing new weeds in our driveway and parking areas (gravel). it does need a second application a few days later to get the few weeds that are not dead. no i did not miss them (i used to have a private applicators license, so i had training) a few will not die. i am providing this review as a Sweepstakes Entry. lower price would be nice.

Doesn't work at all

[This review was collected as part of a promotion.] lowes store recommended me to use this product to control weed, but didn't work well for me. I am not optimistic about this product. Waste of money and time.

Works very well

I have to kill all kinds of weeds in a landscaped area, and this version of RoundUp works the best--it is quick and thorough and does prevent more weeds for quite a while. I also like that it really isn't toxic to mammals, especially after it dries.

Patience will pay off

I highly recommend this product for elimination of weed and grass control. One must be patient though as the final solution will be a few weeks away. It still beats the heck out of pulling and digging weeds/grass up. Should you decide to use this product to eliminate weeds from your yard, careful 'surgical' application must be utilized.

As concentrated as you like

I use the concentrate so I can control the concentration of the mixture. Works as advertised Helps if the grass / weeds are dry.

Driveway

Our driveway seems to be a problem area. This product works. It kills unwanted grass and weeds that poke through the seams in the driveway. Everything looks nicer now, and we won't have to do this again for several months.

Killed a tulip vine

By filling a plastic bowl with alid half full with this liquid. put slits in the lid. Insert the vine chute ends into the bowl and into the liquid. Let them set in the liquid for a week or until you see the chute dying. It will kill all the way back to the main part of the plant. I have tried many other ways to kill these and all have failed!

Long time user

A golf course landscape guy convinced me to use this product. That was five years ago. You must follow instructions and put down a mist barrier over the areas you want no weeds in. I use it in my rose bush and hibiscus areas plus all of the three foot wide stone area around the house. Don't get it on the leaves of your good plants. I spray right to the bottom of my rose bushes. If a weed comes up two weeks from now in the area you sprayed, you MISSED that spot. I live in Southwest Florida and w...

Best Weed Control Product for the Money

I used to live way out in the country and I had a huge garden. I had trouble with weeds which seemed to take over. The farmers suggested RoundUp, so I gave it a try. I have never used anything else. Now that I live in the city, my garden is small. But weeds don't seem to know the difference between the country and the city. They still invade my garden. Having RoundUp at the ready has let me have a weed free yard for over 20 years. I have noticed that some people say they have trouble with it s...

It does work

I have used comercial weed and grass killer and paid alot of money for it. I decided to try round up extended control weed and grass killer. WOW what a difference. The weeds and grass starts to die with in hours. I am saving money by not using as much. It is nice not having to spray every month . That is a time saver. I live in FLorida and the weeds and grass does grass alot. Again this product makes life easier. 1 thing that I have a problem with is: I wish it come in a larger container.
