I've been using Purition since December. The ordering process is simple, delivery is fast and reliable and communication is great. The products themselves are excellent. I buy the discovery boxes as I can't decide on a favourite flavour - I haven't found one I don't like! I find they mix better into coconut milk than into cows milk. That might be because I'm mixing them with a stick blender (Braun) rather than a bullet. I love that these are a natural product not loaded with sugar and sweetener. I'm using the shakes for lunch as part of a balanced, gradual and long term weight loss plan. They are easy, delicious and keep me full all afternoon - so no snacking. Once the packaging becomes recyclable I'll upgrade to my review to 5 stars.
