I came across this review elsewhere on the site from Zoe Cameron and thought it would be of interest regarding this debate. It's her review of the Wilkinet Baby Carrier.
"Most people think this is great but it just wasn't for me unfortunately! I really wanted to love it but didn't. I found putting it on really quite tricky and confusing, and needed another person to help me. It never felt particularly secure on me. My husband seemed to be fine with it but with our second baby we bought a Babybjorn baby carrier, and I prefer it much more. I like the fact that I can put the Babybjorn on and then put the baby in it, rather than having to lie the baby on the Wilkinet and then somehow get it to my chest!"
