I really needed this for my GX85 as my thumb had nowhere to rest (accidentally pressing the buttons all the time because my hands are too big). built like almost everything Panasonic makes. My issues with it are that it doesn't fit snugly next to the top right front of the GX85 (it seems a few millimeters shorter) and you have to remove it to access your SD card and battery. You could design this handle with a cutout for the small battery/SD card door. Also, the wheel you use to screw it to the camera body is small. This wheel would be easier to tighten/loosen if it was bigger.
