Review: buy it. - I was buying RM43 which is incredible but twice the price. I was really surprised at how good this worked. As with the RM43 it takes a couple days to see results the best being when its warm. Its been one week since spraying and it took everything down that I wanted. Really a great product at a great price!!

### ⭐⭐⭐⭐⭐ This stuff works well!
*by R***J on July 22, 2025*

I have a two gallon electric sprayer. I didn't even read the mixing instructions, I just dumped the whole 32 ounces in and then filled the rest of the two gallons with water. Added a half cup of dish soap to it. I spray it on heavy on the problem areas and then at least a small spray on the already clear areas. Even with all the rain this year it's minimized the weeds tremendously. It did take a couple of days to see it working but I'd rather have the long lasting effects this has than the quick acting and quickly disappearing effect of the other products I have tried. Warning: I got a little too close to my grass in the backyard and the rain seeped this stuff into my lawn a few inches. It will kill your grass just as well as the weeds so be warned. I have a lot of rock and gravel areas though and this stuff has been the best besides burning them with my propane torch which I have done before. Less noisey and less dangerous than burning, and honestly seems to last longer in my opinion.
