I got this A/C for my bedroom, about 252sq ft, and it cools it great. Some reviews say it's noisy but it's not as noisy as a regular fan? No drainage problems yet. Only took about 45 minutes to install, just one cut on the window slider & putting insulation around it was the most time consuming part.
I’m terrible with assembly but this was a breeze. ( pun intended). I used a YouTube video to help guide me through the process. Kinda lame it doesn’t come with batteries for the remote but not that big of a deal.
