After a year of use, I can't say that I have any particular issue. It hasn't rusted, but I deducted stars because the phone and its rubber are 100% plastic, which I consider unacceptable for its price. I had to buy a new rubber that has a steel connection, as the plastic had lost its tolerances at the fittings and was leaking water from there.

Extremely short shower column. Not sure who or why someone would want it this short. The tallest part of the column swayed back and forth, no stability or bracket to hold it in place. My plumber had to improvise with old parts to make it functional.
