My 2016 FR Salem Cruise Lite had one, one of the inside knobs stripped out shortly after the warranty expired. Repaired with Gorilla glue, worked until traded. Shower is GREAT, and main reason for trading to a JayFeather 23RL. Same hardware and I will keep my eye on the rubber band, use the wife's hair ties if needed. My main concern is the cheesy plastic in the knobs.
