Initially, I had bought a size I thought would fit, but when I got them, they did not fit snugly. I wrote to the company, within a few days got the shipping label, and after that, I received confirmation that my new bands were on the way. No questions asked. As for the product, it fits comfortably and the colors are as vibrant as illustrated on the pictures. I bought three not knowing if I would like them, but I love them.
