The quality is actually great, but it just does not help much when the size of the bag is way off what it is described to be. I wanted a good bag for my Montage 7, and decided to order this one because it looked like it would be a close fit for the synthesizer as I really didn't want a bag that takes up a lot more space than needed. The space in my car is limited, so this was a very important factor. So when I first tried the bag on the Montage my first thought was that they shipped the wrong size bag. But the tag on the bag said 127x42x16, so I then thought maybe I had wrong measures on the Montage when I ordered the bag and rechecked them. But no, they were 124,5x39,6x131, so it should from what I could see fit pretty good. Since that is not the case I took the actual meassurments on the bag, and they are indeed way off and the bags actual inside dimension is 131x47x18. That makes this bag a waste of time and money and I would have returned it if I could, but since I live in a different country and have paid for shipping and import tax it is better to try to resell it. So my advice is, do not buy this bag if you want a bag that fits a Montage7
