This is what I needed, although the button on the wand does not go all the way down to the button hole on the older wand that it has to fit into (about 1/2 in. difference). The new wand stops before it reaches the button hole. Since it's in tight at this point, though, it probably won't matter. Haven't had a chance to give it a good try, but I think it will be OK. Very glad to have this replacement for my older system.
Works fine with our older system.
