Strong dye

As the description mentions, it has 3x more dying power!
It also dissipates in a few days, so it's perfect for applying herbicides, etc.

Wonderful product.

Excellent value for the price.

Exactly as expected.

This dye was just what I needed and worked exactly as intended. It was a little pricey but I guess that’s just market price now. Great purchase!

It will turn you into a Smurf, but it works!!!

This product worked as intended on my lawn AND gave my friends and family added laughs because it SMURPHED me!

Works as descibed

This product works as described, makes it much easier to tell where you have sprayed and where you have missed. Highly concentrated, a little goes a long way.
