I purchased this a few years ago for our daughters nursery. It is way over priced for something that only makes noise to sleep. If it didn't develop an annoying rattle after being on for on for a few seconds I would've paid [$] for it but it's not of good quality. My daughter doesn't seem to mind but it drives me nuts when we travel I I bring it with us to use.
We live in a house where the noise travels directly upstairs. Bought this initially for our room but now use it in the hallway and it helps drown out the noise from downstairs and lets my little ones sleep.
Noise options are just right.
I was introduced to this little machine at a hotel in San Francisco. It has been the best thing ever. I'm a very light sleeper, and my husband tends to snore. I wake up at EVERY LITTLE NOISE. This has been a lifesaver. I love it so much that I bring it with us when we travel, and I'm going to buy a second one for our baby's room. It's easy to adjust the sound level as needed.
