i have been using the Single Speed version of this (i read reviews by people who stated that there wasn't much difference between the two speeds) for 2-3 years now. I LOVE IT! i was using a fan before i found this amazing piece of gadgetry. It was too cold to run the fan in the winter and didn't want a fan running at the same time i had a heater in the room running too. Hence the best investment so far. It's small enough to travel with, it stays on (no automatic shut-off, no timer, no breaks between songs like on the iPod, etc) and i use it in my son's room. It really is the perfect sound machine. you don't have to worry about overheating, whirring blades or it accidentally falling over. I highly suggest it; the BEST $50 i spent.

I bought one from walmart in the pharmacy section wiht the hairdryers and things like that. I don't remember the make , but it has white noise, heartbeat, thunder, waves, and a bunch of other nature sounds, I think about 10 settings. Battery or plug in, it was about 15 or 20$. Right now it is lost as the older kids will play with it, so I turn on the air exchanger, it will run for about 20 minutes then auto shut off.
The fan suggestions brought back a wonderful childhood memory for me... We had a whole-house attic fan, which was the greatest white noise maker! So loud, yet soothing. Except when the timer shut off and I woke from the sudden silence! I wish we could have one in our current home, but there's no room.
If anyone else has experience with the white noise machines, I'd love to hear about it!
I use the dual speed ones. There's not a whole lot of difference between the two speeds but I like having the option. I try to use the quieter speed for our kids' rooms but if our environment is particularly noisy, I use the higher speed. And I use the higher speed for myself You can also turn the top to adjust the number of openings and that changes the sound volume and quality a little bit.
