Compared to another carrier, we had before, this has the huge advantage that you can wear with a view to the front holding the baby. Whether this is now psychologically problematic, I can appreciate bad because our baby will somehow fill in any psychoanalytic questionnaires and instead happily watching the world while Mom or Dad both hands free. This Velcro strap is also very handy to quickly fine tune the right size. The comfort is also generally quite high. I do not know how this is when our little heavier and bigger, but right now I can wear them once each friend.
The price may seem a bit high, but the quality is also quite good, and anyway: if the child wants to get out always look forward, one has virtually no choice but to wear these. At least one reads yes only negative about the competition from B.Björn.
