Review on Heating Pad for Back Pain Relief: Portable Massage, Fast Heat & Lumbar Support for Arthritis, Leg Cramps, Abdominal Comfort by Barb Bosch

This product delivers goods. It has 3 levels of massage and 3 levels of heat, and you can choose any combination of them including just massage or heat. Depending on the selection, the corresponding buttons change color (red, blue, green) to indicate the selected massage or heat intensity. The package includes a 3000mAh battery, which has a very large capacity. This allows for an operating time of 3 to 6 hours, depending on the mode used. That's impressive for a massage and heating belt. I appreciate the ability to run this device from either a battery pack or a wired AC connection. This gives more flexibility, especially when the battery is low. Premium strap construction. Upon inspection, you can see the quality of materials and workmanship. You can adjust the fit to your comfort level. If you long press the button to turn on this service, subsequent presses will cycle through the three intensity levels. Another long press turns that particular feature (heating or massage) off. Thoughtful design with a simple and convenient interface. I have very positive impressions of the design and performance of this device. It easily meets expectations, conforms to the description and images in the product details. It deserves a 4.75 to 5 star rating with a very high recommendation.
