Great product, and excellent customer service. Worth 6*. There were a couple of small problems; could not apply a discount code and product shelf life. Both were dealt with efficiently, money refunded quickly, I cannot think of anything that they could have done better, probably the best customer service I have seen in the UK, I only gave 4* as the shelf life was not good. It was only 10 weeks from receipt, which seems strange as the product should last 8 weeks even when opened. I am curious if it was older stock, or if it is always short, and if it can be frozen to extend it. Anyway this means that I must order small quantities, and lots of deliveries are not good for the environment as well as being more expensive.
