It took a while but I found the right one. I have a bony shoulder and none seemed to fit me right, and caused pain and left marks on the skin in the wrong spots. This one, however, is soft in its whole body, with a metal core and feet that can be completely adjusted by applying a bit of strength making it suitable for truly everyone. It can be very low, very high, you can bend it to make it curve or flat, and doesn’t ruin the instrument in any way for it has rubber disks to protect it.
Couldn't ask for anything better.
