I want to thank you for producing these life-giving devices. I started using my zapper about 2 weeks ago... in addition to a healthier diet that I had been on for approx. 1 month, lowered my blood pressure and equalized it - I am now 112/70 with a resting heart rate of 66 - one month ago I got consistent readings of 145/90 with a resting heart rate average of 84.
