This little gadget took a little getting used to at first but after my second use, it felt wonderful. Fits comfortably around my neck and the heating function feels amazing. Simple operation and the instructions were easy to read. The beep sound is loud so I can be sure that I can hear the modes changing or the unit turning off. The auto shut off after 15 minutes was a nice touch as well. Small and low profile makes this easy to take with me when I am traveling.
