Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Pleasantly surprised

I was nervous to buy a window unit because after reading all the reviews on Amazon I expected to plug it in and have it not work, sound like a tank, drip everywhere, etc. At first I thought my nightmare had come true (I really didn't want to have to deal with shipping it back) because when I first turned it on, it wasn't working. But I opened it up and found that inside, one of the fan blades was wedged up against some of the metal piping inside. I pushed the pipes aside about an inch and freed the blades. Now it works like a charm.I really like the unit. It sounds like an air conditioner; the noise is a perfectly sensible hum/rush. Air is cold. Remote control is a nice plus. Easy to install. Good stuff.
