Good price and fast, safe delivery.  You can't ask for more.  As for the product, I have been using it for 2 years and will keep doing so.  I have color-treated hair and this line of products protects the color.  I had a quarter-sized bald spot when my stylist recommended I start using the Reviv3 system.  It worked and I am a loyal supporter.  You have to give it time but keep at it because it works.  I started seeing regrowth after about 3 months of use.
