I have had four children and used this sling with the last three.  As far as slings go, this is the best.  The material is soft and stretchy, yet very sturdy.  The many snaps allow it to be fully adjustable.  My babies have all loved being in this versatile sling.  My only complaint is that slings in general start giving me a backache after awhile.  I prefer baby carriers over slings.  But in the realm of baby slings, this one is top notch quality and performance.  It's not overly expensive, but not cheap either.  The customer service is great and overall it's a great buy!
