An excellent product, buy one now.If you are someone who likes white noise while you sleep, this is the device for you. It is small, portable, well-made, has a wide range of volumes, and fairly easy to operate. This device fits in your hand and can easily be packed for trips. It remembers whatever setting it was last on, so you don't have to readjust it every time you unplug it and plug it back in. The construction seems solid and put together with the intention to last; this is not a cheap feeling product. The sound output can go from quite quiet to almost too loud, so virtually everyone should be able to find the setting that is right for them. Initial setup is a bit of a hassle, what with going through every one of the noises, but once you find the one you like, you can just stick with it forever.There is a 60 minute option on the device, which shuts it off after an hour, but I only ever use the continuous sound with the simple on/off button. The 60 minute option does work, however, as I've tested it just to see. What I really like about the continuous sound from this device is that it never loops or has any pauses while it restarts--it's just uninterrupted white noise going endlessly. It really is great.While you might think 50 bucks is a lot for something that just makes a repetitive noise, you sleep every single day. I've had this for several years now and it is still going strong, so that means I'm paying only a penny or three a day to help ensure a good night's sleep. I'd call that a solid investment. Do yourself a favor and buy this product. Your well-rested morning self will appreciate it.
