While ago I bought myself a sleep sound machine with only 5 sounds but eventually gave it to my Dad to help him to calm his nerves and fall asleep. Mom was in the hospital for a while and he was anxious being alone in bed.
So I got myself this one and I was pleasantly surprised with the sound quality and the choices it offers. This machine is slimmer than my previous one and I like the way it looks. My previous one only had nature sound, waves, rain, while noise and waterfall. This machine has 20 sounds: Pink noise, Gray noise, Brown noise, Lullaby 1, Lullaby 2, Lullaby 3, Fan, Craking fire, Clock ticking, Train, Crickets, Frogs, Birds, Rain, Thunderstorm, Stream, Ocean, Shush, Womb Sound... It has an auto/off timer that can be set for 30, 60 or 90 minutes.
I enjoyed it not for long lol. Outside by my husbands window nested a naughty bird who would sing at night and that was bothering my husband. I mean it sounded beautiful but too loud to his liking and I offered him my sound machine. He was like "It's not enough that this bird is annoying me you wanna add some more to it" He is a stabburn mule sometimes but I convinced him to try it anyways. Next morning I got a message from him saying that he slept like a baby and thanked me lol
its been weeks since that bird moved on but my hubby doesn't seem to be wanting to give my sound machine back lol. He got used to sleeping with it an it's OK with me, at least he gets to sleep well and have a clear head while at work. If I have a chance I will most certainly get the same one again for myself and won't give it to anyone lol.
Highly recommend this particular machine
