It works, but still can fail / fall off randomly.
Bought this for an elderly relative and installed it on a clean flat (non title surface) in the shower. It worked for about 1 week with only very limited usage (basically 2x) then it randomly fell off by itself. Since then it's fallen 2 more times on it's own. My suggestion is that each time before you plan to use it for a shower, check the light indicators and give it a slight tug to check for sturdiness. I would give this 3.5 stars, because it's not 100% reliable and I wouldn't put someones entire body weight on it.
