I am using LG window ac model number LWA5BP3A for quite some time now. It is best product when compared to other brands at this variant level.
Cooling is excellent. It has timer, so you can be alot more relaxed while sleep. Saves electricity as I am using 5 star rating. only one issue I think is that window ac makes alot of noise. but this is problem of all window AC. I will recommend anyone who is looking to buy window AC, go for LG.
