This was the best $20 I’ve ever spent. My daughter will having crying fits at times after she’s fed and changed but the minute I start playing this she goes quiet and starts to fall asleep I attach it to her car seat when we go on rides or when she’s fussy at home I attach it to the mamaroo where the little mobile is. I have a hatch also but that’s in my room so this is easier without having to unplug the hatch so if you want a small portable sound machine this is it 😁 sound is very good for the size and it has multiple sounds comes with a charger cable to recharge it. At target for $20
