Bests & Worsts Reviews from Amazon

I have four of these. I love them. I give them as gifts to every friend who has a new baby. My first was for an open office to help drown out private conversations from a nearby kitchen that I really didn't want to hear. My second was for my first baby. We got a third when my second was born and finally I got my own so I could sleep through my husband's snoring. They're great. Until they rattle. There's nothing more annoying than an inconsistent rattle. Determined not to spend another $50, I unscrewed the bottom of the worst offender. It was filled with dust. I cleaned it with compressed air and put the smallest drop of silicone lubricant, that specifically does not attract dust, onto the base of the shaft that the fan sits on top of. I let it penetrate for a minute, turned it on and the rattle was gone. $50 saved and I'm in love again.
