Nice, but two-speed superior
The single speed conditioner was ok, but mine had a hum I did not care for. Upgraded to the two-speed, and found it 5-star all the way. It goes with me every time I'm away overnight. Personally find that with very little tweaking it masks out noise from traffic and neighbors, and dulls cycling loud air conditioners common in many hotels. Again, if you are here because you are thinking twice about spending extra for the two-speed, I found it well worth the upgrade.
