I have a stereo pair of Minis in my master bathroom mounted to the wall and there’s a single Mini in the kid’s bathroom mounted to the wall. Showers are daily occurrences in my house in those two bathrooms. No issues for at least a year. Don’t even use the exhaust fans a lot of the times (have them connected to a smart switch that turns them on automatically at or above 60% humidity)
Previously had an OG in my master bathroom and that worked perfectly as well.
