I purchased a Qi shield 6 months ago. The difference it makes is phenomenal. I live in a highly toxic emf environment that is saturated by dirty electricity and extreme strength Microwave Frequencies. The Qi shield has been a life changer. My health is so much better and I sleep so well with it next to my bed. I would highly recommend Conscious Spaces products to anyone concerned about the dangerous levels of MW and EMF frequencies we're all currently exposed to. They are literally saving lives with these products. I'm so grateful that I discovered the Qi shield as I've spent so much over the years without any proper difference until now. I also thank Tara for fantastic customer service. She went over and above to make sure I got my Qi shield much quicker than I was expecting. Thanks so much :) I'm so very grateful and so happy - I would highly recommend Conscious Spaces to anyone who is seeking a device that actually works and helps to facilitate optimal health. Thanks again from a very happy customer :)
