I purchased two wraps and found them to be really helpful. But I really want to leave a review about the customer service. For some reason, one of my wraps would not work when pugged in. I emailed the company and they responded immediately with suggestions on how to check if some of the wiring got loose. The wiring was not the problem. When I emailed them back, they again responded immediately and offered to replace the wrap. In this day and age, it is often difficult to get a company to respond when there's a problem, much less in a timely (ad kind) manner. Will definitely order from them again and recommend them to others!!
