I love this product! It has so many options for massage and pain relief and you can adjust the intensity from slight to WOW. The battery is awesome! It came with a full charge, I have used it many times and it is still at 100%. I don't think the charge icon is broken or incorrect because it does seem to work as well as it did the last time I used it. The downside is the touch screen. It only stays on for a second and you have to keep tapping to get it back on. It has a lock feature so you don't grab it and change the setting, but when the screen is black, to activate the screen you have to tap [too] many times to get it back which changes modes and stops the timed therapy completely. This product works! The pain relief it gives is awesome!
