********Update: Sarah has said that now that she has used the Pognae for awhile, that she has noticed it is shorter than the Ergo and she thinks Grace will outgrow it faster. Still, she is happy with it.
Sarah has a review of the Pognae Baby Carrier, available on GMarket here in Korea. It is cheaper than the Ergo and has some extra features and cuter designs.
I have the Beco (4th Generation) and Ergo. I like this style of carrier because it is easy to use, secure, quick to get on and off and it is comfortable to carry baby for a long time.
If I needed another carrier, I would try the Pognae.
