If you're trying to find good deals on used brand name products -- how can you be certain that you're buying a real product? Like for example, phone cases, screen protectors, for your phone -- in this case, Incase (no pun intended haha). Does Amazon allow sellers to use the names of real manufacturers to sell fake or look-alike products? If so, how can anyone be sure that they're purchasing the real thing? Usually, I look at several things before buying something on Amazon. 1.) How many number of ratings that seller has (the more the better) 2.) The average rating (the higher the better) 3.) The customer reviews/comments But I've read in some of the comments of the product that I'm interested in purchasing, that it is a "cheap imitation" of the real thing. How are people allowed to get away with this on Amazon?
