I have these as well, but they suffer the same underlying complaint that the majority of the dial area is for temperatures that are generally unwanted. As far as I can tell (and as the article records) there is a relatively small range of temperatures people want for showers or whatever, and then all hot and all cold.

So while with my setup I press a button and (sans hot water reaching the shower time) I always get the same temperature, dialing around to get that temperature is still fairly annoying.
