Description:- Scott and I have been searching for an answer to this problem for some time. Several months ago, while at a trade show, we saw a demonstration we couldn't believe. Two guys at the Sanctband booth would take a piece of their tubing, cut it nearly completely through and then ask you to try and break it by pulling and stretching it. Scott and I both tried - couldn't break it and were very impressed. We now offer the stronger more durable Sanctband resistive tubing with our Strong Arm device. Our Strong Arm will now come with the orange (medium) Sanctband tubing and we'll offer pink (light) Sanctband as and option.
