I got this as a gift for my babies, who are not born yet. When I opened it and tried it, I loved it's cuteness - what a beautiful choice. It adjusts the colours according to the room temperature, blue (cold), white (suitable), red (hot) - though it could be a bit bright at night. I also like the four sounds' feature (2 lullabies, heart beat (like they were used to hear their mum's while in the womb) and white sound-which I presume reflects the sound in the womb) and turning on any of them on the duration that you prefer: 30 mins, 60 mins and continuous.
I started using it at night and nap time while I'm still pregnant, because I want my babies to know the sounds beforehand and be comfortable, not annoyed by them when they are born. I want them to like it because it's a present from their wonderful aunt & uncle.
ProsBeautiful light - temperature and music - sounds
ConsMaybe price is a bit high. However, if your babies like it and if it lasts forever then it's worth every penny.
