Works Very good
I had a very slow drain in my shower that I had tried other products to unclog with no success. I tried this product and it worked very well. The instructions are good as you mix with water in bucket and and pour in the drain. Simple as that as you do not need to run water in drain after awhile as with most drain cleaners. I put in at night as it suggested and t he next morning the drain worked very well. I would recommend this product.
