The reason I bought this bag for my Tyros keyboard was to take up less space in my vehicle. Because I used to drive a van with plenty of room, but nowadays I simply drive a car with a lot less room. The bag itself is quite tough and well padded. But with taking the instrument in and out of my car, the stitching around the zip became undone and I ended up having to sew it by hand. So in my opinion, the zip stitching needs to be stronger, perhaps with thicker and stronger thread. As I have said, apart from this, it's a good protective bag.
