Bests & Worsts Reviews from Amazon

Arrived on time. I'm a smoker (cigarettes, what were you thinking?), and the smoke used tovwaft in the air of my studio apartment like floating sheets. Now? All gone. I can have baked garlic and anchovies for dinner and, within 15 minutes, you'd never know (unless you kissed me, of course). Whisper quiet unless on the highest setting. Four stars instead of five because the "air quality sensor", which supposedly adjusts strings based on air quality, is . . . eccentric. A summo wrestler could fart straight at the machine and it wouldn't notice. But in the middle of the night -- no smoking, no cooking, nothing -- it will decide the air is foul and turn on high. Always curious: just what does it sense? Sound sleep?
