With any Flash Storage, if the deal looks too good to be true, then it is.
Don't believe too-good-to-be-true prices. If you're having a problem with appraising the value of Flash storage, then google 1TB, 256GB, 125GB, 64GB, and so on down that path. Even among different brands, the prices of legitimate flash storage doesn't stray too far off from the norm. Also, NEVER, unless you have a good reason, buy Trans Flash on eBay with anyone less than a feedback of 1000. 1000+ Feedback shows that a person/store is a professional, legitimate shop suggesting that you'll get what you paid for. If you're buying Trans Flash at a cheap price from someone with 50 feedback, then that suggests theres trickery afoot. Even if they have 100% positive feedback, you have to be open to the idea that their customers are either fake, or are too dumb to know fake Flash Storage from the real thing. Don't trust the extra low prices on Amazon. I myself played the fool by purchasing an SD card that was nearly half priced and could tell instantly when I started using my product that I've been sold a fake. You must also be open to the idea that even if a store is legit, they too can make the mistake of unknowingly stocking fake Flash when they thought they were getting a good deal buying in bulk on sale. Actually the only time I recommend buying from eBay is when large online retailers like newegg or buydigg is having a sale, and even then the most you'll often ever save is like 35-40% off.
Ebay and Amazon does refund you though when you're reporting counterfeits.
Another indicator of a scam store, is if you email them asking for a refund because you suspect counterfeit flash, they'll refund you your money to prevent you from reporting them, even they don't tell you to send the item back. A real store demands you send them back the product so they can claims it and report on it, while a counterfeit store gives you a refund instantly and doesn't ask you for a return. They're trying to make you happy so you don't feel compelled to report them, so they can still continue to sell their fakes unhindered.
So basically if you're willing t play the waiting game, you can "buy" a counterfeit flash storage from a store you know isn't legit, then threaten them and tell them you know their secret, and then they'll refund you, and you have a free counterfeit. Nearly all the counterfeits I have in my house say 32GB but are really 1GB, and in the end I always got back my money on all of them anyways.
