Query: It's worth every penny spent!

We appreciated this easy-to-assemble product, which took one personless than half an hour to put together. It is very versatile and can be used for a girl or a boy. We liked the nightlight rdature, which offered a handy way to keep baby's sleeping area gently lit. The soothing lullabies, nature sounds and vibrations helped to lull my little one to sleep. I could rock my son back to sleep not only without getting up,but even without as much as lifting my head from the pillow. And when I wanted to get some more uninterrupted sleep in the morning, my husband was able to take him in the Portable Sleeper to another room.This sleeping system is one of the best available on the market today.It's worth every penny spent!
