Had anyone used cocoonbaby for their newborns? Did it help with colic?

I have never heard of this cocoonbaby and did a quick search from google. Wow, the price is very steep and it seems baby will outgrown it very fast once they can flip at 4th month old. From the product descriptions: CocoonaBaby is being used in baby nurseries and maternity wards, as it procures the feeling of containment it is used to, having just left the boundaries of his mother's womb, and feels comforted, reassured and will help him adapt as well as possible to his new life; The child adopts a semi-foetal, cradled posture, which reduces skin problems that could trouble the baby in its first months, reduces uncontrolled twitching of the limbs which can wake the baby up abruptly, it limits the risks of flat head syndrome, It improves both the quality and the length of time that baby sleeps and can be used day and night from birth onwards up until the time it begins to change its position independently (approx. 4-5 months) It is more for baby's sleep instead of reducing colic. Also, colic happens due to infant's growing digestive system with muscles that often spasm and a still-developing nervous system that causing tummy gas. It has nothing to do with sleeping postures. Here is a discussion thread on how to relief baby's colic using natural remedies.
