Decided to replace the terrible showerhead in this house (a rental, sadly, or I'd have done it long ago) with something nicer. So I bought one off Amazon last Thursday, it arrived same-day, and I was able to surprise my wife by having it installed before she got home from work. She loved it.
This morning, she showered and went to work. I went into the shower, tried to adjust the angle, and it came off in my hand. Realized that a plastic retaining ring that held it on to the ball joint that it rotates around for adjustment broke. Finished my shower with the high pressure spray coming out of the ball joint.
Oddly, I noticed at Costco last Friday that there was a Kohler one on sale. ~3x the price of what I bought from Amazon. But at least I trust the brand. And it's one of those fancy ones with both the rain head and the wand.
So I ran over there during lunch, and the crisis was averted.
