I bought as a surprise birthday gift for a friend. She absolutely loves it and thought it was a very wonderful, unexpected and practical gift. She was already trying different combinations and has it on her desk during the day, taking it with her on her daily walks and said she will love it on trips. She is having so much fun with it while she feels it is helping her be healthy and refreshed. She is enjoying using it so much and is also having fun trying some of the recipes and different combinations. I can only relay what my friend has said about your product and it has all been very positive and thanked me for having such a unique yet practical gift to her.
