Pros: Unlike wraps, once you thread your sling, you're good to go with only minor adjustments needed the next time you want to use it. It's pretty easy to get the hang of (as in, I only had to watch the tutorial video once) and there are multiple ways to wear your baby including front, back, and hip. I love that I can wear my 20-pound 9-month-old on my hip just like I'd carry him, but with hands free.
Cons: For more physical activities, you might want a more structured carrier. The bulk of the weight falls on your opposite shoulder with the hip hold, which can get tiring.
Weight limits: Newborn to about 35 pounds.
Tips and tricks: It's easy to clean by throwing it in the washing machine with a sock over the rings.
