I like this sound machine a lot, it is very small and fits nicely on my nightstand; I like that it only takes up a small space; it has 36 sounds but only a few works for me for falling asleep but the ones that do are very effective. I am really happy that I can set a timer for 30, 60, or 120 minutes and the good news is that the timer works effectively. I will be using this a lot to mask background noise. It is also portable and comes with a USB cord for charging. Overall I really like this sound machine.
