Query: Piece of junk!

Vicks claims this unit is 20% quieter than previous models, what did the previous model sound like? A jet liner? This thing had to be designed by an engineering drop out, the fan is made of all plastic and it warps after 3 hours of being on after which point it starts to come into intermittent contact with the unit itself causing a clunking noise. It has so many "lights" on it it literally lights the whole freaking room up, I had to get tape out and tape the the freaking thing up so I could sleep in a dark room! I also paid a 100 bucks for this piece of garbage at Target, so yeah!
