My belt worked fine for the first two weeks and then the reversible buckle stopped turning to the black side. I emailed the company and they told me to get harder. It did not work. I issued a refund because the seller didn't fix the issue. It worked again the day I wanted to return it. It worked for 2 weeks and now that I have 3 days until my return date it is blocked again and not working. Very disappointed with this product.
