Bracelets are very good. The cotten ones are a little hard to put on and take off. Other than that they are really good. Customer service is amazing. I originally wanted to return the bracelets because I didnt think I would wear them enough. Once they got back to me they told me that international shipping would be really expensive and offered me 50% of my money and i get to keep the bracelets which was a fantastic compromise. Very impressed.
