Review on Yogasleep Nod White Noise Sound Machine: 20 Sound Options For Adult & Baby Sleep Aid, Night Light, Sleep Timer, Nature & Pink Noise, Noise Canceling Privacy For Office by Kaushik Hall

1. The nature sounds are on short loops (like 10 seconds), not at all non-looping.2. Some of the white and brown noise sounds have a weird higher pitched whistling tone on top.3. Some of the other pink noise and Dohm or fan sounds have subtle chime tones (kind of like an elevator floor chime), very subtle, which also loop every 10 seconds or so.4. The color of the light is basically off-white. Only at the lowest brightness does it appear as pictured.There are so many issues, I wonder if I received a knock-off. So I requested an exchange though Revain. The replacement I received had the exact same behavior. So I'm returning it and will buy something else.
