I posted in another thread, but thought this deserves its own post.
I recently bought an ergo carrier. It came directly from China (with DHL) so I thought it was weird. I emailed Ergo and they confirmed it's fake. I had bought it on ergocarrrierusa.com which I thought was their official website but it turned out to be one of the many fake websites out there.
There are very few authorized Ergo retailers. However, the list of known/suspected counterfeit ergobaby product website is ridiculously LONG:
Aside from the quality of the packaging, I honestly cannot tell the difference between the fake and real carrier. However, I do know I wanted a real Ergo that is for sure safe for my baby.
