Doesn't fit impact driver

I had hoped the colored sleeves would work like a locking bit holder or the button on the back of a ratchet to lock the sockets in place. Not so; the ball in the side of the square drive is properly spring-loaded, but the sockets just pull off as with any less expensive socket adaptors. More important is that they do not properly fit and lock into my impact drivers. I must, therefore, hold the adapter in place for use.
