Customer feedback highlights perceived moisture control and suitability for safes and other confined spaces. Some customers describe the bags as easy to recharge and long-lasting, while others report durability problems, bags breaking open and melting in a microwave. Those concerns matter because this product is designed for repeated reheating. The listing claims a heat-resistant fabric and window, but that claim does not resolve the mixed reports.
