Rating : - Machine does not work
I initially purchased a machine through Amazon and it quit after 6 months of use. I love the white noise aspect for sleeping both at home and on the road so I ordered another which arrived and does not work. Fool me once, shame on you - fool me twice, shame on me. Never will order again.
