"Hi there...Just wanted to write and tell you I bought a silver cross pendant and Q-Link for my laptop in March 2018. I was suffering from weekly terrible headaches (at least one per week) for the past two years. I spend most of the day in front of my laptop at my desk. I was spending about $200/mo getting neck massages and going to the chiropractor for adjustments. I bought these two items and since March I have only had 2 bad headaches. I don't have to get weekly neck massages or even get adjustments anymore. I kept waiting for the shoe to drop and for the headaches to return. But, they have not!!!!! I could not be more happy with these products and am telling all of my friends about EMF and how to protect themselves...GREAT products!!!!"
