Works!
I love this!  I realized that sitting at my computer made me feel weak, and using my phone, tablet and ebook made my hands tingle.  I told my acupuncture doctor, who pulled one of these pendants out from under his shirt.  He tested me as sensitive to my electronic items, and strong when his Q-link pendant was on me.  I purchased this while I was still on the table.  I wear it all the time and I feel so much better.  I can spend hours at the computer now without feeling sick.  Awesome little gadget that has changed my life!
