I just got an email from Amazon stating that my review of the pump did not meet their "guide lines" and will not be published. I guess that if you say that Amazon is selling counterfeit product, with photos and evidence of it, they will not let you post it...
There is no evidence. Its just your observations. It may or may not be a counterfeit. For all any of us know they could make them in 2 different factories. Did you try and contact Carter and ask them?
