This case is light and very convenient. I've had it for two and half years now and it has done an average of five gigs a week so it's had plenty of testing. The handle is very comfortable and the M20d fits snugly and safely inside. However, it's no flight case, and it's starting to show serious signs of wear and tear around the edges on the base. I've re-enforced it with tape, so I hope it will last another year. Even if it doesn't, I would sooner buy another one of these rather than a flight case as it is so light and convenient ... not to mention much prettier than a flight case.
Top quality zip, top quality material and workmanship. There is a "separator" inside made from the soft material, which keeps M20d knobs and button safe. Also, has a one pocket for power and usb cables. Perfect for car (bus, train) trips. Although, I am sure if this bag works with the flights (I would not recommend it definitely).
