I discovered PainPod products over a decade ago. Since then I have acquired many of their products, with no regrets. Their effectiveness in managing my pain is extraordinary. The products never fail and I use mine everyday and for many hours. PainPod is definitely worth the extra $ for such premium long lasting products. I cannot wait to see their product line expand and improve in the coming years. PainPod delivers and does exactly what it says it will do. In my opinion it exceeds expectations and any other supposedly comparable products on the market.
