I initially saw this on a The Gadget Show and was initially sceptical. I decided to buy given their money back guarantee and did find the first few weeks a little challenging as my sleep seemed to get worse ( this did however give me hope as if it was an empty box it would have had no effect!!). Anyhow, after about 2 weeks I suddenly noticed I was beginning to sleep all night, uninterrupted. This was massive news for me and hadn’t occurred for many years. Slowly, but surely, my sleep has got better and better … not 100% but at least 80% and improving. I still get the odd bad night but it’s getting rarer and rarer. I also monitor my sleep score via my Apple Watch and there is no doubt that it has improved. I would not be without my Zeez and tell anyone who has similar problems, all about it. So glad I watched The Gadget Show!!
