We've recieved the Beco Butterfly Baby Carrier at our baby shower and have been using it for 7 months now.  I'm a petite 5'1'' and DH is 6'2'' and the Beco is great for both of us!  My son loves being in this while at the grocery store, running errands, at the airport or going hiking!  The padding on the shoulder straps and the good lumbar support make this very cuomfortable to wear.  I always feel my baby is safe and secure in the Beco.
