Like many of the brand's products, I am completely satisfied. It is strong, the fabric of good quality, clean, strong seams. In addition, it can move to the washing machine. It is very comfortable (as the previous model I had the same brand: ONE) and feels no discomfort or pain to the weight distribution of the child. The clip system already present on my other model is very comfortable to put (it should still have the hand) and very safe. Two position: front or behind. For now, my son is too small to go in my back, but in a few months will be the case. A star less because my other model can wear baby in front facing the road and not to me (which allows the child to see and enjoy some of the landscape), but also because it does not completely defeated. One side has a clip, but the other is sewn. On the one hand it allows baby wear faster but to ask the child when sleeping is more delicate. Otherwise, like all models of the brand, we can go there with confidence. This is a very good high quality product, comfortable and safe.
