The air conditioner itself works well. The only problem with this product is it's connectivity to Wifi so you can actually control it on your cell phone. If you have a 5 GHZ home network, this unit will not work via wifi. It ONLY works using a 2.4 GHZ home network and doesn't give you an alternative method to connect in a different way. It's really disappointing to buy a smart a/c and not be able to use it's features. Really defeats the purpose!
