    Great Service

    Verified Purchase

    I haven't used this product yet. When I received the product, the container leaked in the plastic envelope and I lost 1/4 of the liquid and the instructions. I called and the young lady was pleased to email me instructions and credit my card for 1/4 of the product lost. You don't get customer service like this too often. I will use the product in the spring. Thank you for your great service, I will order again from your company.
