Thank you for the heads up will keep it in mind.
My switches have been mostly okay, my daughter's room the "up" part really takes some effort or it doesn't work. It was kind of acting like that at the beginning though - I may replace it. The other switches seem to be fine. I have the U/L listed V2 switches (other versions are ETL) - they have been working for about a year or so.
The V3 switches/dimmers have just recently been installed for the other project. Have not had any complaints so far but will keep an eye out as still very early in the game.
Maybe @agnes.zooz has some thoughts on this.
