I don't have any customer call back complaints but I picked Dimming - does not turn on at lowest setting even though that it was not exactly true.
I put some dimmable LEDs in at my own house and the only thing I don't like about them is the dim-ability at the low end. I only care a little to nothing about how dim they are when I turn them on, I care a lot about how low I can dim them down and the current crop goes dead before I get them as dim as I like.
