The FeiyuTech WG2X gimbal's power/mode button is easily pressed if transported not in a purpose built case.   It can also be easily depressed while in operation.  This model adds a ring around this button making it recessed and much less prone to being inadvertently depressed while being transported in your gear bag or even while out riding on the trail with it.

I used 3M 468MP double-side clear adhesive tape to affix the protector around the power button.
