Cons

- •A few reviewers mentioned that it doesn’t work well on deeply ingrained or tough weeds
- •Limited capacity (only 2.5 fl oz), which might not be enough for larger areas

Bottom Line
If you're already using the Ortho GroundClear system and need a reliable refill, this product is convenient and effective for broadleaf weed control. However, if you're dealing with tough weeds or large areas, you might want to consider a larger or more potent weed control solution. For an easier, ready-to-use option, you could check out the original GroundClear product, which many users find more versatile for broader application needs.
