Best Money can buy !
I got this as a bonus from buying the purple bio mat on 26 Jan 18. I did not have any high expectation of this because of the negative reviews that it is very hard and uncomfortable.  Yes,it is hard for people like me who always love latex pillows. I convinced myself to give it a try because of all the listed benefits of using it. It took me a few days to adapt to using it.But once I got used to it, I will not switch back to any soft pillows because it is very supportive The negative ions generated all night long help me sleep better and my chronic migraine headache has been greatly reduced. Imagine this- you can sleep better, and decrease your migraine headache without using any drugs or even electricity for the rest of your life....I am sold and I ordered another one 3 days later for my sister on 29 Jan 18. My sister caught a bad flu lately and she couldn't even get out of bed on the worst days.So she didn't wash her hair for a few days.To her surprise,her hair didn't smell or stuck together like it should be. The negative ions generated from the pillow helps - just like the negative ion machine helps clean the air. What more can we ask for ?<br />Don't hesitate to get one for yourself or for your loved ones.Andrey,the CEO of MediCrystal, has provided one of the best customer services I have ever seen.If you don't like it you can return it but I bet you won't.
