I purchased three units at the same time at the beginning of 2021 so I've had them for quite a while and they are pretty awesome, I love that you can connect with the smart app and integrate them into your smart home, very important feature to have nowadays, so using them for the past year and a half has been a joy they've always worked and like most air conditioners they keep my apartment nice and cool and there's not much else I can say, another great LG product, I bought an LG microwave that is now 10 years old and still operating and will be purchasing an LG in the future
