Pros: Easy to use, comfortable, great for tiny babies
Cons: Not great for bigger babies for long periods.
We put this sling on our registry and until recently it's been the most used of all our carriers. It's easy to use, comfortable, and the baby can sit in numerous positions. My husband loved it because it allowed him to get work done around the house with the baby in the sling and it was invaluable for those early months when our high-needs baby refused to be put down.
As the baby gets older you can transition to hip carries, but I found it's just not comfortable enough for me to do serious baby wearing anymore. We use the Ergo for long walks now. But I could easily walk 3-4 miles with a newborn in this sling.
It's high quality material, excellent padding, and easy to adjust. The Dr Sears Baby Book helped me learn the different holds, which was helpful at the beginning. I highly recommend this sling for new parents.
