Did you mean on how to spot counterfeits? First the keyhole orientation needs to be compared to an original model, that goes for all the qualities. It's not hard to figure out, but some of the top class counterfeits are very hard to spot; the handle is a teller for new models, if the telescoping handle can only adjust to two positions on a new Rimowa, its a counterfeit. If the telescoping handle adjusts to any position, then it is genuine, also loose tolerances are a indication of a counterfeit. What I have observed with Westerners is they tend to be more willing to pay MSRP as a personal anecdote. Do not pay MSRP; that is a rule of thumb. 60% off or more is a good deal, for parallel imports you only pay roughly 30% more than the top grade counterfeit, but you get a product identical to the ones sold in official shops. Many Japanese businessmen know this trick of getting parallel import goods as opposed to buying in-store. Most haven't caught on yet in large numbers.
