- anecdotal, but in the several years of using amazon, never had a problem with any of the 'non-amazon' sellers. There are ratings for a reason. That's like saying you didn't get what you wanted from one ebay listing so all of ebay is bad
- reviews don't mean nothing..what's your problem with the current reviews. Like anything you read, take it with a grain of salt. Amazon also includes verified reviews, as in, people who actually purchased the product. Search google if amazon isn't enough for you
- based on the rest of your post you ordered what you thought was an arduino from a non-amazon seller off of amazon, found out it was a clone, and was pissed cause you thought the reviews would have made that more clear
