Review on KES 16-Inch Shower Head Extension Extender - Rainfall 🚿 Shower Arm Flange, Stainless Steel in Matt Black Finish (PSAN4-BK) by Jeff Prabhu

I installed this shower holder in my camper. After using it for a month I was driving down a bumpy road and later that day I found my shower head in the shower tray. The shower head fitting has come loose from the shower holder. As you can see in the photo, the threads are a bit rusty. Any attempt to screw the fitting back into the shower head will result in the fitting being pulled out. The threads don't stick at all. I had to take the whole shower head off and find a better replacement. To make matters worse, a dropped showerhead left some shavings in my shower pan. This is going to be a lot harder to fix than just replacing that useless shower mount.
