What Customers Are Saying

The product is effective at killing a wide variety of weeds and grasses, including stubborn ones. It is easy to use with a convenient spray applicator, and the concentrated formula means a little goes a long way. While it may not work immediately, most reviewers found it started showing results within a few days to a week, with the weeds and grasses turning brown and dying off completely. Many noted it was safe to use around desirable plants and flowers. Overall, the product was highly recommended by most reviewers.

Kills fast, outlasts rain.

No-pump sprayer is a hand saver. My wife is convinced that this works better than Roundup and I’m inclined to agree.

Works well, but takes a while to show.

Would Recommend

Works great at killing weeds and grass. However, it took 5-7 days to show any effect. At one point, I questioned if I had actually sprayed the area. Then, a few days later, the weeds started to yellow. Afterward, the affected areas were completely killed. I would recommend the product.
