Mophie was another one that had years of problems for fakes
That doesn't account for all the listings that were sent the wrong item for years as it was coded wrong or packaged wrong and Amazon continually did not fix. For 3 months they were sending out Fitbit Ones that were mispackaged in error and were burgundy instead of black. People would complain and they resent the wrong one again cause they just grab and go. Another issue when you just have one listing you go off of.
Just a sample across a few product brands of people that typed in there item hoping to find the real thing front and center. Obviously you only have one listing to type in on Amazon as that is how the format is set up (even that can be debatable on certain products). Ebay was never set up to be a one listing format. It was a place to sell some collectibles or items you no longer wanted for some money. It was never set up to be a place to sell new goods in volume. Like everything it evolved over the years and grew as well. When Amazon, and others came into the market it forced the BIN options and change to storefronts more than it had before. Which brought in manufacturers, box stores and everything else. We all know everything has changed the last 20 years and this is where we are at now. Been good changes and bad changes but both formats have there issues and always have. To sit there and say they have no fakes it pretty ridiculous. It has always been two different markets. There is much more you can do with ebay in terms of parting anything of value out or salvaging something for value that you could not do on Amazon. I've seen people make a living parting Dysons out down to every single piece and getting triple retail for them doing that. Amazon is great for moving new product in volume among other things. At least with ebay you can see the item is a fake for sure if you know what you are looking for versus just blindly buying under a listing that is supposed to be what you want although it might not be what you receive. Either way the buyer is protected on both formats as we have all seen. Both formats have there share of different versions of scams, different versions of random suspensions or gates / limits so everyone just needs to do which format suits them best. One thing I can guarantee is if anyone has been in this long term we all started on ebay at one point and probably all made decent money there which got us all interested in finding other avenues to do online sales. That is where Amazon is great as people with daily jobs can also have a full time business with FBA and try to juggle both sometimes making more in their FBA ventures than there jobs. That is a great option to have these days.
