**EDIT** more on this Here
unfortunately i hadnt seen the existing discussions on here until i'd already won and paid my money for a sandisk ultra II 2gb compactflash card.
card arrived today and it's definately fake based on the comparisons shown on this site ...
i was thinking it may be worth making a sticky to warn people of the inherent dangers of buying memory off of ebay. i know all purchases on ebay should be carefully considered before bidding and i'm certain plenty of people will post in this thread about how they 'never buy from ebay', but for those who do use ebay its near impossible to tell before you buy if the product you receive will be genuine or not and as such are not as easy to spot as your typical scam and can even catch savvy users such as myself off-guard if not aware of the scale of counterfeiting going on.
the info in the other threads is also rather scattered so perhaps we can use this thread as a central place to put any information on how to go about getting your money back if you already fell foul of this scam and also how to tell if the cards you use are genuine.
