This is a pricey product and meant to protect your pricey product. The insides are well padded and there is ample space to pack things like USB cables, DC adapters, etc. There are wheels on one end in a vertical orientation, which is a bonus and the product along with a 61-key keyboard inside can easily rest vertically in one corner. Overall, its 5 stars.
It fits in everything including the music stand of my PA900. Perfect bag. Maybe a few roller wheels would had been an advantage. A little tad heavy, but necessary. Fits in the car only after folding a seat of my Ecosport. The advantage over the hard case is that it is a few inches lengthwise smaller than the hard case of Gator 61 or fitting it into my car would had been a hassle.
