I bought weed and grass killer concentrate 1 gallon, I mixed as directed and waited for weeks no result, roundup Is the best product out there works fast, never buy again!

I've been murdering weeds with Ortho Groundclear concentrate now for two years. Make sure you follow the dilution directions and be patient. It's good stuff.

This product is the worst weed killer I've ever tried.. the bottle said see results in 15 minutes….NOT didn't see any difference for several days!!! Mixed as directed also…I do not recommend this product!!!!

I've used this before but living in New England it Does not last 1 year. Why?....We get cold weather here and snow in the winter. You have to reapply each spring to fall if needed. Not Ortho fault.

I used this product 3 times. Waited until ground was dry and no rain in the forecast. Absolutely did No improvement. Weeds grew !!! Looked like I fertilized them! Would not recommend!

Does NOT work! I purchased this product multiple times over the year, hoping it was just a fluke...it is NOT. Also the comfort spray handle quit working, replaced batteries, primed, cleaned nozzle, I know about the lock...etc..... When the spray handle did work - it just dribbled out. I wasted a lot of my hard earned money on this product and I am not happy.

Purchased today. Comfort wand is nonfunctional even after AA battery change. Wand makes noise but does not spray, despite the cap being set to on, the safety lock being set to unlock, and the nozzle being set to spray. Troubleshooting requires direct contact with toxic substance that spills on hands. Overall extremely disappointing.

Fantastic product to killer those nasty driveway weeds, have a very long driveway and 1 application starts killing within the 15 minutes as stated on bottle. I do use the concentrate for my stubborn weed trees and Johnson grass( note cut to base then spray-gets to the roots fast on a hot day). I have tried others but Ortho has my back and kills them weeds. Now I may need a 2nd application for emerging baby weeds after a rain storm. Weeds seem not to come back and my driveway stays weed free all summer and fall.

I sprayed this along a fence line in my development. It didn't kill any of the different weeds. To be fair most of them were mature when I sprayed so I want 100% positive it would work. I also sprayed a strip of grass that was 4' x 60' and it didn't touch it. I walked around my property and sprayed lots of small weeds in places like a rock bed and driveway cracks. Not one weed was killed. I'm guessing maybe it was a bad batch but I can't be sure. I picked this based on a friends recommendation after using other brands for years.

[This review was collected as part of a promotion.] This weed killer does its job fast in getting rid of nuisance weeds and grasses where you don't want them to grow. Seems to be long lasting after treatment as well. Easy to use via pump sprayer and directions are clear.
