I purchased and returned several slings before trying this one.  The Infantino Sling Rider was hated by our second and third child.  The Boppy sling was too awkward for me, and being short, I couldn't find a "setting" that didn't leave our baby dangling in front of my thighs, rather than my torso.  I bought this as a last resort and I am REALLY glad I did!  The adjustment feature rocks!  Unlike the HotSlings (which we also tried), I don't need another size for my husband.  We have 3 children all under the age of 5, so he will more than likely be using this sling, too!  With the adjustable strap, we can both wear this sling comfortably and the adjustment is easy breezy!  I also like that it comes in so many patterns - again, makes it less weird when hubby has to wear it.  :-)  The best thing about this sling is how comfortable it is for me and baby!  The other slings made my back hurt within 15 minutes.  I felt like I was hunched over or leaning back to try to distribute the weight better.  With this sling, even my crooked spine feels fine even after 30+ minutes.  I don't feel strained at all.  Our baby SCREAMED when we tried the other slings (and we had them for several days and made several different attempts).  When I put her in this one, she fell asleep.  She snuggled right in and just passed right out!  I'm stoked!  The ONLY thing I am not crazy about is that it DOES seem to be very warm.  The Boppy sling had some mesh in it to make it more breathable - I am not sure if this sling will work in the heat of the summer, but we shall see.  So far, baby and I are HUGE fans - I don't know how I would ever be able to keep up with our 2.5 and 4 year old without it!  One last thing - the price.  They seem to cost the same everywhere I found them.  Initially, I was hoping to find something cheaper.  However, after buying 3 different slings that WERE cheaper and being so displeased, I am very glad we spent the money to get this one!
