After months of daily use and abuse, it's working well

The first was defective, and I emailed the company. They were responsive, polite, and sent a replacement immediately. Be forewarned when initially turned on it can suddenly get too hot which is the only reason to 4-star it. Otherwise, it's a 5 star. After months of daily use and abuse, it's working well and doing its job! The longer length allows me to wrap it around my knee or place it across the width of my back.
