I got this to replace a different sound machine that started dying after 4 years of everyday (12+hour) use. Both of my daughters have used white noise machines since the day they came home from the hospital. Unfortunately, our daughters share a wall, and the 10 month out is LOUD when she is not happy. This sound machine has been great to help with dampening her loud voice so our 4 year old can get some sleep. We love that this sound machine is loud.We got this last night, and it took me a couple of minutes to set up after reading the instructions (YOU MUST READ!). I like that all the settings (sound, volume, timing) is set, and I don't have to fidget with it every time. We use the white noise sound, LOUDEST setting, and timer off (she uses the white noise all night long). I tap and hold the metal piece on top for a second and it turns on and off without any issues. The little light is pretty cool too, but I don't think we will use it as we have a salt lamp in our baby's room for low lighting.Totally recommend if you want a LOUD white noise machine for a decent price (I got it for $20).
