Generally, a very good buy
I used the White Noise Sleep Machine as a travel alarm clock on a recent camping trip. I was pleasantly surprised at all the functions available. It is compact, with an easily readable large number display. The battery seems to last for several days. It has a very large selection of soothing sounds: nature sounds, bird sounds, and music, and I like the adjustable sound turn off delay. The alarm function works well and the time is accurate. I also like the temperature and humidity information. The operating Instructions are a little difficult to follow. I wish it had a 12 hour time format, and the night light function only lasts for 30 minutes.
