Bests & Worsts Reviews from Amazon

There is a pamphlet in the package that says I can get a free sample of other lawncare products if I go to their website to make a request. It turns out that I will have to write a 5-star review in order to receive one. That's why you should not trust the reviews of this product, or for that matter, all products under this brand. So you may ask, did I actually use the product? Yes I did. I used it with MSM, a herbicide. There was absolutely no difference in terms of effectiveness than the last time I applied with the herbicide alone. A brand with great products should not need to bribe users into giving them good reviews. I have no more confidence in this brand.
