The carrier was pretty easy to use, I could carry my 17mth old, 25lb daughter fairly easily, and it was a good price.
The only weaknesses I found were:
- As others have said, you can't put the leg away when you've put it on, which makes it cumbersome (in fact it's a bit stiff when you've got it on the ground), but you learn to work with it
- The shoulder strap adjustment is quite stiff, and I found the comfort to really depend on adjusting them right, if it were slightly too tight or loose it was uncomfortable on the shoulders, but once in the right place it was fine, so make sure you practice a few times to get comfy.
Otherwise, I'd recommend it to anyone!
