Query: Disappointing

I've been a big fan (no pun intended) of Vornado air circulators. I own a couple of different models but this is the first time I'm not happy with the product. Although there's only a few parts to assemble, putting it together took a lot of effort because of poor design. Getting the parts to fit was so much harder than it should ever be. Secondly, when the fan is tilted at certain angles you can hear the blades slightly rubbing against the inside of the fan.Do yourself a favor, don't buy this model.
