I was very pleased at how quickly my Vulcan resistance band arrived in the mail. I've used it for mobility/stretching/accessory movements 5-6 days a week for the past month and there are zero signs of wear and tear on the band. All of the other resistance bands I've had in the past became dirty/grungy or left an unpleasant rubber odor on my hands after use. The rubber of the other bands also started shearing which compromised the elasticity and safety of the product. I don't have any of these issues when using my Vulcan resistance band and I'm pleased that it is of much greater quality than the other bands I've used.
