I give the product 4 stars. However, I give the shipping and customer service 1 star. After I ordered the Pure Light, they shipped me a nice box that contained a lot of air and the free mini-product they give away. The packing slip included both products. Because I didn't want to spend my time on the phone to correct their mistake, I sent two emails to find out what happened. No reply. Finally I called and was told that they ran out of the Pure Light so just shipped me the free mini-product. It would have been nice if they called me, wrote me a note, sent me an email, or something what explained what happened. I guess I wouldn't have received the product if I didn't call them. Great customer service. I did finally receive the Pure Light, which is nice.
