I saw this ring sling on ebay
http://www.ebay.com/itm/NEW-RING-SLING-Baby-Toddler-Carrier-Wrap-BROWN-DOTS-/120961742248?pt=LH_DefaultDomain_0&hash=item1c29e1b5a8
And I am wonderng if its comparable to the more expensive ring slings out there? I have a sling by seven slings which I got for free but its not adjustable so its kind of annoying and the fabric isnt too great. Anyone havea success story with non-name brand ring sling like this ebay one?
