This has been terriblying for me to use this ratchet socket with any ratchet handles because they couldn't detach this socket every time even though the handles have detach button on themselves. Detaching every socket has been forcing me to use like a metal flat head driver for prying them off. It hasn't been able to detatch them only pulling them strongly. If there will be an opportunity to improve them, don't dig all faces on inside of them which the rachet head will be set. Only one or two faces should be kept the flat faces.
