Product shipped right away and received within 5 days of ordering. Immediate follow up cal from customer service the day after I received the product wanting to know if I had any questions. That was helpful, would be nice if they would follow up again in a couple weeks after you have used the product. The product is pretty easy to use after you get use to it. There are a couple downfalls. 1) having to take an hourly dose during the day gets hard, especially if you go somewhere or are out for awhile. Going on vacations with this product is also somewhat frustrating. You need to pack an extra bag to take all the product with you, and if you are not near the product at your specific daily times ( morning, noon, night ) it's hard to take your drinks. They say you can premix your daily drinks and take with you, but it would be nice if there was an alternative.
To keep cost down they use one size container for all the powder, which makes it somewhat difficult with the containers that are only half full upon arrival. I would also suggest using a towel when putting the powder into whatever you use to mix it with, otherwise you may have powder all over.
