We've been using the Crib Light for a couple of weeks now. Our child is getting out of the crib stage, but this light has made a huge difference. The tones aren't harsh or too bright, and you can choose from almost any color on the spectrum. We don't use the motion sensor feature, but if he was smaller then it would be a huge help to check on him while he's sleeping throughout the night.  We have had zero issues with the wireless controls, but be aware you have to have a wireless network to communicate with the light and take it through setup.  I would strongly recommend this product!
