One of the worst suppliers I had to deal with, communication was a nightmare always cold from the sellers side. Anything relevant I mention always used to get ignored. There was no passion no enthusiasm at all. I only took the risk as they appear to have over 10 years experiece and I thought that lack of basic human feelings were caused by ignorance due to the seller believing they are better than the rest.  Long story short I took a chance and the product was awful, all 3 flavours tasted awful, when mixed with water it doesn't mix well at all, the taste was 80% tap water (which i added) and under 20% flavour. When i try to address these issues to seller they literally could not care less. Alibaba had to get involved to initate a refund. Please do yourself a favour and avoid this seller like the plauge. They are not worth your time or the impact it will have on your mental health
