To avoid these kinds of mistakes, make sure to closely examine a product's packaging. Often, a close look at the ID code a manufacturer uses to identify the product will clue you in. If you see models with similar, but not identical, ID numbers, ask about the difference. If the vendor you're buying from doesn't know, make sure to check out the manufacturer's website for product specifications, or consider calling its customer support line. It may save you from paying today's price for yesterday's technology.
