Anyone use cocoonababy from red castle? Is it really good and worth for buying?

I don't have any friends who tried this, but have read a lot of good reviews online. Seems like this product is used in hospitals in France as well. One good thing is that it is portable and can be placed in the crib. The drawback is that it usually only fit newborns and up till around 3 months and baby would probably outgrow it.

We didn't go with the cocoonababy but the sleepyhead instead. Similar type product, but not as a reflux aid but as a cosleeper. It saved us during sleep regression and really helped with his transition to the crib from his Moses basket.
