What’s the rave on these things?!? WHY should I purchase this?!

I already did lol BUT I bought it because I heard gathered name a lot and I had a coupon that was going to expire so I bought it and figured I’d return if I don’t like what I research or hear.

I have read mixed ideas that this is not meant for co sleeping- however the lady at buy buy baby directed me to it when mentioning co sleeper? So I’m a little confused. Anyway, what’s to love about this product?
