Well I have two Reo Grands. One has the button cover and the other does not. I purchased one from Rob but it must be just a little to larger because is slips down after I put it on (Using the tube spacer) and then of course you can't push the button down. I do like the button on the one I am using but the other one must just be slightly to large. Just took it off and have it in a drawer so ideas to prevent this would be helpful!
