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 to be weak and unreliable. Many complained it did not work as promised, taking days to see results or requiring the entire bottle for a small area. However, a few customers said the product worked great and was affordable. Overall, the consensus is that this is not a high-performing weed killer, and customers may have better results with other leading brands.

Good killing action.

Works great on weeds and grass. The pump spray looses suction easily.

Great sprayer and weed killer

Would Recommend

This is an easy to use spray. I was surprised at how powerful the spray was compared to the brand I used to use. It took longer than I expected to kill weeds but that could have been the crazy March weather. By the third day the weeds were brown. The small weeds died first and then it killed the dandelions! I'm about to use it again in a different spot that gets more sun.
