I have the brown Alex. And I love it. I looked at many carriers and KB is the way to go. Rosie is great in the carrier. Never makes a sound. I sneak her in lots of places!
I liked the look of the Alex because it looks like a purse. I wasn't sure about the material at first but it really is fine. I wanted the black but brown was in stock. So that is what I went with. I really thought I wouldn't use it much but I use it a lot. It is nice to have when you need it. I do agree with Couversmom, with Rosie (5 1/2lb) it does get heavy after a while. Ryan is definitely the person to order from.
I spent days debating over the KB. Her is my advice.....Just Do It!!!!!!! You will not regret it!
