This is my first LG purchase and this LG A/C meets what it claims.  
After careful study from different users comments,  I decided to spend a lot (more than what I planned) for window A/C for summer 2020.  Since we are more home during 2020 (due to Covid),  it was in use almost 24hrs a day for hot summer days and kept its performance as claimed.  I love the feature where you can control A/C from phone app and able to get the room cooled when I get home.  Electric bill was lower than 2019 even though I was using more A/C for summer 2020.
I hope this will last me for a long time.
