I bought 6 of these a while ago; Aramis, Drakkar Noir, Polo, Silver Mountain Water, Polo Double Black and M7. Now, I've never tried any of these in original form, but thought they'd be worth a punt for the money. And generally I would say they are. They are very moisturising, made with essential oils, vit E and a base of skin toner, the scents are fairly long lasting too. Though, of the ones I tried I would only buy the Aramis and M7 again. Simply because I'm not keen on the scent of the others, they're nice just not me!
M7 is supposed to be a very masculine scent (Fragrantica website review) the 'smells like' is actually quite floral, though very nice. The Aramis is a good 'manly' scent, very 'leathery' which I like. Double Black smells like Addictions Wild Ginger, Silver Mountain Water smells like hand cream, Drakkar Noir smells quite 'soapy' and Polo is very vetiver/cardamon based - not to my liking.
Overall, I'd say if you're in the mood to experiment a little, or if you have a favourite and would like to see how 'smells like' compare, they're well worth the money. I'll certainly buy more in the future.
