We previously purchased an LG Portable A/C a few years ago. When our older (non LG) portable A/C recently, it was a " no-brainer" for us to get our second LG Portable A/C. We have been VERY pleased with our new LG Portable A/C. It keeps our upstairs bedrooms and hallway cool and works just like it's supposed to. Again, we are very pleased with BOTH of our LG Portable A/C's!
