I would return it personally, for two reasons. Like the pp said, it's still a "crotch dangler" style. For a newborn, it looks fine, but as your baby grows, you pull the bottom strap out to adjust it and the strap gets thinner to fit between baby's legs.
Secondly, and this is huge to me, the baby's weight is still all carried on your back. Carriers like the Ergo rest on your hips and it makes a huge difference! I'm not carrying DD while I'm pregnant, but before I got pregnant, I could carry 20 lb. DD for hours in the Ergo without being uncomfortable. When she was much smaller (maybe 10-15 lbs.), my back hurt after 20 minutes of wearing her in the original Bjorn.
