Have you ever recorded a video and it came out shaky, either because of wind or just holding the phone too long? Now there is a handheld device that enables you to record on your phone without worrying about being steady and balanced. It's called the Steadicam VOLT. It can be used on any smartphone including smaller phones like the Moto E or larger phones like iPhone 8 Plus or the Note S8.
The VOLT comes with an engine for stabilizing even the shakiest hand. The counterweights allow for non-powered balance during your recording. You can move about and never worry about your picture being distorted or off-balance. It uses a lithium-ion battery with an 8-hour life and the battery charges fairly quickly.
