My four year old so far loves this sound machine: has white noise, projector, and night light. I have to agree with the other review about it not having a charger outlet end. With it having just the usb port, I thought I could charge it and my child could use it on the top bunk. Instead it has to remain plugged in all night, which seems odd it not having the house plug in end. I had hoped to avoid a cord. However, last night, I noticed the turtle turned off. I thought this machine could run all night plugged in and I will have to investigate, perhaps the timer function was hit. We purchased this as we have a newborn and wanted something portable and fun to help drown out the crying at night for our four year old. We have other marpac sound machines and really like them and have purchased some for gifts as well. I overlooked the fact it had to remain plugged in and so am a little disappointed in that but otherwise it is a cute sound machine.
I brought this little turtle for my spare bedroom (the little's room), which I turned into a grandchildren's destination. The turtle was a great investment. I purchased my first sound machine over 35 years ago from this same company (abet the original company name), and it still works and is presently being used by one of my grown daughter's in her counseling room. This little turtle works even better than the original as it has the original white noise, an array of sounds and music you can choose from, a night light and the ceiling projection of stars. Probably the only thing I will not utilize is the red light for the stars (too scary, because kids think of fire, perhaps in the future you can change red to yellow, white or purple), but I will use the blue and green colors. I also wish it came with a charger plug (the cord has a USB port on the outlet side, but no charger). These are the only two reasons I gave it 4 instead of 5 stars. However, if I needed another one or if I have a baby shower to attend, I would and will definitely buy this little turtle again.
