Review on 🏃 XCELER8 Bands Speed and Agility Training Resistance Bands for Enhanced Sports Performance, Inclusive of Ankle Straps, Training Videos, Fast Sprinting, Explosive, Agile, Strength, Endurance by Matthew Outlaw

I received this product with high and moderate expectations. The construction is solid and I was impressed with the results (serious muscle activation) after the first and second workout. Unfortunately, on my third training session, one of the yellow straps broke. By design I don't think this should happen unless inferior materials are used. Each elastic band is covered/protected by a stretchable non-elastic fabric sleeve or cuff; This sleeve naturally limits (and I assume it is by design) the distance each band can be stretched by the fully extended length of the sleeve. The only way to stretch the band beyond this limit is to break the sleeve. In my case, the tape broke in half inside the sleeve, and the sleeve remained fully intact and now does not resist! Therefore, despite the success in design and functionality, I have to give low ratings as the engineering and durability of the product seem terrible and are destined to render this product useless in a short time. Disappointing product, positioned as "a system with very solid performance". :-(. Hopefully this part will be replaced under product warranty. *Update* The company contacted me and provided a replacement strap under product warranty with no issues. It means a lot to me when a company is willing to stand behind their products/services For this reason I have increased my rating to 3 stars If product and/or warranty support is maintained during the warranty period I will give a full 5 stars.
