Anyone use the infant NightForm positioning pillow? Does it work? - ＮｉｇｈｔＦｏｒｍ

My daughter does always 3 weeks before the end, when I kill, and always turns his head to the left when I saw myself on the right side. Then I noticed a flattening of the head on the left side a little and do not want to really deteriorate. Has anyone had the same problem, and uses the positioning Night pillow shape with excellent results? Or maybe a few others (perhaps less expensive, take the form of Night positioned for 45-50 $) pillow? Or maybe a few more tips to solve this problem? My DEP recommends the pillow, but I would like some comments from parents who used the pillow like.
