Haven't had the chance to install this on my new DW yet, but it appears to be sturdy, the part that slides back and forth appears to work without effort and I'm sure it will keep everyone from having to ask "are the dishes clean"?  Best advice, set it to clean when you start dishwasher and back to dirty when you clean out dishwasher.
