This is a great product! Is highly durable, easy to use and just an all around great band (much higher quality than the products i have bought at some chain sporting good stores). The only reason i gave it a four star rating is because after i bought this product, i actually ended up having to buy the adjustable set because i needed to have something a little more diverse for my p90x regimen. But thats more of my fault than the products falt, lol.
