What Customers Are Saying

The product has mixed effectiveness, with some customers reporting it worked well to kill weeds and grass, while the majority found it unreliable and not very powerful. Many said it took longer than promised to see results, and some felt it did not work at all even after multiple applications. The product is easy to use but may not be worth the cost given the poor performance for most customers.

Kill tough weeds

Would Recommend

I needed to kill wild morning glory. A very tough weed to eradicate. So far it is working. But the infestation was so bad only time will tell if I win this war. But this is the only stuff so far that the wild morning glory didn’t just suck up and keep growing.

Got a month for weed kill to work?

Would Not Recommend

This product takes weeks to work, and then does not kill every plant. It gives plants time to put out seeds and reseed the weeds.

Maybe does not work

Would Not Recommend

The advertising cannot be trusted. The product is not very fast if it does eventually kill the weed. I sprayed some weeds in a paver patio. Tey all appeared to be vibrant for the next three days. Starting on the next day some started to appear sick. Two days later is apparently a slow death if in fact it does kill the weeds.
