Bests & Worsts Reviews from Amazon

I ordered 2 of thef 32GB 2x packs. Of the four cards, two worked briefly and then upon trying to reformat, I received "card error" on a Fuji X-T20, a Canon T6s and a Canon 6D. The cards are clearly bad. So, given that 2 of the 4 are working (for now at least), just multiply the cost of each card x2 to factor in a replacement and you might be ok...
