Xiaomi Yi camera hardware mods. Aluminium case.

I got aluminium case with UV-protection filter kit from ebay. 

Pros:

• It looks great due to semi-gloss black anodized aluminium coating.
• Very easy to install camera into it.
• Protection of camera lens and body.
• Shoe mount on top - great for dashcam use.
• 5 1/4" mount holes on the sides.
• It gives better grip for the camera.

Cons:

• Kit filter shows severe vignetting. 
• Shoe mount and 1/4" holes on the upper and lower sides are not aligned with optical axis of the lens.
• Suggested camera fixation method doesn't provide a solid result.
• Mic hole of the camera is blocked by the frame.

It seems like the manufacturer of the case uses preforms for one of GoPro camera. That's why there is a mismatch of mount and mic holes. So I recommend not to rush off with buying of this case and wait until some design adjustments to fit Xiaomi Yi will be made.
