I have never bought one, which I didn’t even realize until I read your question and I contemplated my answer.
I must add that generally speaking, I have never been a proponent of air conditioning. That’s probably because I grew up in a place with a cold climate for much of the year, we went without it in any home we lived in, and I found it unappealing in those school, workplace or other settings. Even on cars, I rarely use it.
