YU SLEEP レビュー 

I purchased the 6 bottle package trusting their website that agrees to a full refund if not happy within 60 days. I replied at the end of the first week that it was having no affect on my ability to sleep and I asked how I could return the bottles for a refund. Their response was a list of questions to make sure I was using it correctly. I responded right away that I was following their instructions, but it didn't work for me and that I still wanted a refund. Since then they have refused to respond to my emails.06
