I was carrying ds in it (he's around 17 lbs. ?? and 8 months) and I noticed something looked funny, so I looked down and it looked as if I'd forgotten to do the top snap. Actually, the material that holds the snap tore from the main frame!! Good thing I had the back-up snap on or he'd have fallen out!
Just another reason to always use all the safety features. I emailed the company. we'll see what they do..
