Review on Robust EVA Hard Case for Zhiyun Smooth 4 Smartphone Gimbal Stabilizer: Ultimate Travel Protection & Storage Bag by Ryan Marx

This case is perfect for the Smooth 4. It basically has the same layout as the foam case that comes with the Smooth 4, with a few extras. It's slightly lower and has a pocket on the top flap. I was able to put the USB cable and microphone holder in this pocket and still close the case. Since I use the USB cable pouch, I was able to use the USB cable slot to store the counterweights. It's durable but probably not as reliable as the original foam box but much more comfortable. $13 for this is a great price.
