This thing is a life saver! I walk around the hospital very sweaty. So I bought it and figured I'd give it a try, even if it's just a cheap plastic toy that doesn't last long. But I'm happy to say I was wrong! It is very strong, the bending part is very flexible, not hard and difficult to bend. Color Modes: Solid Aqua or Rotating Rainbow Colors. It has 3 speeds and even the lowest keeps me warm. It comes with a USB to Micro USB cable (1ft) and charges quickly. One of the best buys!
