I didn’t really get a chance to try this product out and see how it works. After ordering and returning a few times, I gave up and went to Home Depot to buy a similar type of product which aerated the soil in a different way. The package would come in and always be missing pieces that were needed for this product. I am not sure about the quality control, but it seemed that not one package had all the necessary components for this product. The only positive was that they did not give me too much hassle to return the products.
