Still, counterfeits are rarely made as well as the authentic product, so if an item doesn’t meet the standards of the manufacturer’s other products, you should be suspicious. Check the tags on the item too. Typos, misspellings, and poor printing are warning signs of a possible fake.

You should also look at the packaging. New products should come in the manufacturer’s packaging, and include whatever manuals or other printed materials you would normally expect with the product. Though they can be faked, too. Typos, misspellings, and misprints are signs to watch for.

If you do find that you’ve purchased a counterfeit item, contact the seller and Amazon immediately. And don’t keep it to yourself. Fakes hurt shoppers, the brands they knock off, and Amazon. User reviews—real ones—are vital to keeping a marketplace healthy.
