Bests & Worsts Reviews from Amazon

Another counterfeit item from Amazon? I have a 50% failure rate on getting items that are obvious fakes. This card was sealed in the cardboard packaging, but cutting it open shows the plastic sleeve holding the card is sealed with a piece of scotch tape. The card itself barely gets 1/2 the rated rated speed on USB 3.0 ports with the right adapter. Other flash memory works correctly at rated speeds. Be careful and check your memory, commingled inventory means that Amazon can have fakes.
