surprisingly a winner!
Bought this for my partner who broke his back years ago and suffers from stiffness and pain especially in the colder months. He’s been using the disposable heat pads which he said have been great but add up quickly. He didn’t have high hopes when i presented him with this belt but has been pleasantly surprised at how effective its been and how long they stay warm for. He reported that the first time he used it, it took a while to heat up but the second time was far faster and warmer. He’s going to continue using this as therapy for after exercise to relieve the pain and has recommended to a friend of his who also suffers from back pain.
