Opinion on the Infantino flip carrier?

I'm looking online at multiple carriers to try and get some price points and everything, the Infantino flip carrier shows tha baby's legs spread apart what seems to me to be support the thighs a little and spreading the legs apart, and on the back position it shows an older child with legs hanging down.
Can anyone explain it to me or give me some input on what you've found best for the amount your spending on it and how log you wear it for and how durable it is.
