The build quality is fantastic on this gimbal, the ability to mount accessories are excellent, the inclusion of a cold shoe mount is perfect for an external light or mic. The battery life is good and nice that it's a replaceable battery!!! It does the job well stabilizing the phone, but the app has much to be desired. It is also a bit bulky, but I guess it's to be expected for 2 handed operation. But overall excellent buy for the money.
