The apparatus as a whole (Castle / cable / stainless steel rail) is very chic and feels safe and stable, but are more minuses for use with MacBook Air:
- The rail causes the MacBook does not sit back, but tall (hugely annoying when something attached sideways
Tipping the MB)
- When closing the MB rail rubs against the steel frame of the screen (I have here two ugly scratches arisen!)
- Just rub the lock in open / close of the MB on the back of the MB screen, which makes also scratches
Conclusion:
Send apparatus, but with MacBook Air: Stay away!
