Nice device but I’ve got three issues with it: 1. The lowest speed is too fast. Why is it faster than the first speed of the original (silver) Hypervolt? 2. The battery life is too short. It doesn’t last long enough. Use it on speed 2 for a little while and that’s 45 mins of battery life reduction right away! 3. It’s a bit shaky in the hand, especially on higher speeds. It doesn’t adhere that well on the skin for that reason. And last but not least, considering the price, it should really come with a carrying case…..
