Bests & Worsts Reviews from Amazon

I purchased this SanDisk Extreme Pro 128GB SDXC UHS-I Card (SDSDXXG-128G-GN4IN) on June 14, 2018 because it was supposed to be suitable for recording video in 4K UHD. Unfortunately, I failed to heed all the warnings about counterfeit cards. Fast forward to this past weekend when I first tried to use the card in my Sony a6500 camera to record my grandson's birthday party. Camera would not recognize the card as a class 10 or better and would only allow recording video at 1080i resolution or lower. Upon researching probable causes, I discovered that I have one of the cards with a yellow lock which is an indicator that it is counterfeit. To be sure, I tested the card with SpeedOut v0.5 and achieved a whopping 15.673 MB/s read, and an 8.878 MB/s write speed. To make matters worse, I am beyond my return period so now I am stuck with a worthless card that, at best, is a class 4. Obviously this card is being misrepresented and some bait and switch tactics are being used on the unsuspecting public. Furthermore, Amazon should be ashamed that it allowing this to happen!
