This is a great gimbal - it feels like metal, is a nice weight, has a great zoom wheel and you can connect it to your phone's bluetooth to use it as a shutter button. Button in native camera app. I'm also very impressed that it works just as well on my Android phone as it does on my iPhone. Pros: The gimbal feels solid and holds your phone very firmly. Can be used as a remote shutter release. Large selection of pan and roll axes. Has a grippy silicone surface. Removable/replaceable battery gimbals are available on the market. The app works well with Android and iOS. Cons: The range of the tilt axis is not great. So if you don't hold the gimbal straight up in pan follow mode, the gimbal will reach its range limit.
