If you're not familiar with the Zhiyun Z1 GoPro Gimbals, you can take a look at some previous articles here and here. The New Z1 Evolution GoPro Gimbal is pretty much the same gimbal with the same performance, but they've added a few changes to improve over previous models.

One upgrade is the new bracket design that requires only one set of screws regardless if you have the Gopro Bac-Pac or extra battery mounted or not. The second addition is a 1/4" threaded mount under the handle. This makes it easier to mount to a variety of extension poles, monopods, suction cup car mounts, etc. They've also added an AV output for Xiaomi yi action cameras so you can use an external monitor.

Power switch on the side of handle.
GoPro chargeable directly from gimbal power
