I own them already for 2.5 years and it has survived even 2 MacBooks.
Beautifully compact, great design and robust + quality workmanship. The MacBook fit in very well and is super protected by "airbags" ausßenrum.
The endurance test I was able to do today, unfortunately. You know it so, you are in stress all packed into the car and then can stop times the MacBook encouraging roof lie?!?! (Yes, the television scene over which one laughs and says that you can not be that stupid ... but it's still :-P). Well I can only say that the MacBook overthrowing 50 km / h from the roof into a 90 ° - survived curve completely unscathed. Only the bag has unfortunately gotten a few scratches but nothing really wild (one sees hardly).
Conclusion:
Forgetting MacBooks encouraging roof -> Klops aufn mind
The bag -> 50
The silly face is flown in the rearview mirror as the MacBook -> priceless ;-)
My recommendation: buy buy buy !!!
