Snoo This is the main unit and the regular belt. I purchased this item, which had been used for about 2 months, and used it for about 2 months myself. Thanks to this, my baby's tossing and turning decreased, and I was able to sleep peacefully. There are some fold marks and fine fiber stains on the Velcro parts, but it's still usable, so I'm offering it to those who are having trouble with their baby's sleep... *Please understand that this item has been stored at home before purchasing. (There are no pets or smokers in the house) I will fold it up small for shipping.
