Are YOU KIDDING of course i did………WOW! You probably know but i actually live on the italian boarder so we go to italy to buy coz it`s cheaper than france. i bought a 6 euro bottle of vodka filtered it twice and compared it to a russian vodka a friend gave me for easter, no difference! if anything the GK filtered gave me less of the “tete de gul” (hangover in french) even convinced my sceptical friend about it. So good work boys i`ll distribute my cards and try to spread the GK word over here! Salut!
