Received in advance and not at all disappointed. Product quality, very durable and well thought out. Super convenient (with a little practice) because not need to nodes and avoids tangling brushes. Many colors available more attractive than the other short there is something for every taste. Easy machine maintenance. Ability to use 1 or 2 according to the desire scarf and can be used in different ways to adapt its position to child development. Can be even used to breastfeed her child as was my case. Keeps baby snug against you. Significant element, allows to have her child almost be having the arms free for shopping for example. This avoids going to and from the stroller and the car can be cumbersome quickly has some busy places. Very effective in calming the baby during colic.
