Fiber strand length: Fiberflies contain strands of many lengths with the shortest strand being 1 foot and the longest being 6 feet. The overall length is about 6 feet long, from handle to tip of the longest fiber.
Battery life: PixelWhips don?۪t dim over the life of the batteries like the older FiberFlies units! However you?۪ll know when the batteries get too low, because PixelWhips will start blinking and mutating the standard color modes in hypnotic ways. It?۪s a neat way to know when it?۪s time to change the batteries, or maybe just keep playing for awhile longer coz it looks crazy!
