In number of cases, individual might face a "fake" watered down product, which in most of the cases is just a waste of your money.Read feedback comments.some neg. comment is your number one attention point to consider.Next on most of the cases if you are bidding/buying a tester you probably will be getting genuine product, but without the original box. Well, what will be considered more important in over all- real cologne or perfume or just a nice sealed box?! Fake perfume will have low quality not just a bottle and the sticker on the bottom of the bottle, but nozzle and pump would not spray strong and directed spray, instead it will spray wide and not powerful stream, or you might have to pump a couple of times in order to get one time spray result, be aware its most likely a fake product you have in your hands. Some of the fake colognes/perfumes might also carry a real and genuine outer box,but also check for the clear plastic cover over the outer box.Genuine cologne/perfume has very tight clear plastic wrap rather than a little loose and very easy to oen on the folded corners, this is not genuine product, be aware. Over all, watch also for the price, if it sound too cheap than in the dept.stores it is probably fake one, because genuine cologne/parfum does cost money, and it cannot be cheap sometimes close to 50% of the real price, be aware. In last, you can get a genuine cologne/perfume from an individual seller, who may not want to use it any more, but please ask him or her where did they get this product before bidding/winning on their item. Good luck on your search for "real" product, hope this can help someone who is not aware of fake cologne/parfum products available online.
