What Customers Are Saying

Customers praise this weed killer for reliably eliminating over 200 broadleaf weeds like dandelions and clover while leaving grass unharmed, with many reporting visible results within days. The hose-end applicator makes application straightforward, requiring no special equipment. Most appreciate the coverage efficiency, with one bottle treating up to 16,000 square feet. Some report inconsistent results on sensitive grass types like St. Augustine or with stubborn weeds like crabgrass, particularly when directions aren't followed precisely. Overall, most customers consider it an effective, user-friendly solution for lawn maintenance.

Dissapointed

I am a repeat buyer

It worked well on my yard and was easy to handle and apply due to it being concentrated and its small size. I am a repeat buyer.

Application was easy

[This review was collected as part of a promotion.] Application using this product was easy and the product worked as expected. While I didn’t notice a difference over other weed killers I have used in the past- I was happy enough with this one as well.
