I agree. The U shape is a gimmick, but a good one. It helps it be quieter inside, but even outside they are quite quiet. I have whole house AC, but I like the windows open, I like being hot. Just not when I’m sleeping. Basically only downside is a truly terrible app that is the only way to access just a few features.

Terrible doesn't begin to describe that app. Honestly what does the turbo button in the app even do?

I have one in a room on the far end of the house that the main AC can't reach, it helps reduce power usage since I can keep the rest of the house warmer.
