I am so glad I decided on this sling.  I tried 2 others: the INfantino Sling rider (Which only satisfied my newborn for a week) and the HotSling, too stiff and no adjustable straps.  I ordered this solely based on the picture and that it's endorsed by Dr. Sears.  I got lucky - this sling has been a GOD SEND!  IT's my baby's favorite way to sleep.  She was very colic-y from the beginning and this was the only way to calm her down and get her to sleep. We would swaddle her and get her in. We'd even lay her down after falling asleep safely in the sling still into her crib.  It's been perfect!  I'm still using it with her at 7 mos.  True, if  you have back problems, it's prob not going to be a positive experience for you.  Also, baby may not take to the sling right at first, but keep trying it and she'll eventually cozy into it. Take this sling shopping with you, to church, to friends, restaurants - it's perfect for nestling baby so she feels safe.  And you can try other positions and styles of wearing it as your baby grows.  I rec. getting Dr. Sear's Baby Book as a companion to show different baby-wearing methods that work with this sling.
