The Amster Difference Our commitment to quality means using superior materials. The Amster heating bag features a plush velvet exterior that eliminates the need for extra covers or towels. Inside, our specialized heating gel holds onto energy more efficiently than water, providing a steady, soothing temperature that lasts for hours. Versatile Relief for Every Need: Whether you are a professional athlete recovering from a workout, a woman seeking relief from period cramps, or someone dealing with the chills of winter, Amster provides a safe and easy-to-use solution. Its flexible design allows it to contour to any body part, ensuring the heat goes exactly where it's needed most—be it the lower back, neck, knees, or shoulders. How to Use Your Amster Bag: Place your Amster bag on a flat, stable surface. Connect the power cord to the bag first, then plug it into the wall. The indicator light will glow to show the 2-minute heating process has started. Unplug the cord once the bag reaches your desired temperature. Enjoy hours of cordless, soothing warmth.
