Review on BOYMXU 32GB Memory Card - Professional 1000x Class 10 U3 Card for Computer Cameras and Camcorders, Up to 95MB/s, Green/Black by Kris Martin

I am a student and I bought this for my video production class. The cameras we use require a specific type of memory card, so I was happy to see that this card was affordable and had mostly good reviews. However, I only got two weeks out of this case. I was able to record two homework assignments and upload them to turn in, but on the third with the card, only three of the dozens of clips I recorded were actually on the card, and when I tried to pull out those three clips on my Macbook, it said it would convert, then there was an error, and then all three disappeared. They reappeared after I removed and reinserted the card only for the same thing to happen. It was the same with everything else on the card: nothing, not even the videos that were fine the week before, played and everything disappeared as soon as I tried it. And when I tried to eject the card, the computer said it was still running a program when it wasn't, so I had to force the card to eject. This happened on all three computers I tested this on. The card had plenty of space and was used exactly as intended, meaning it's not just user error. So now I have to find another card when I'm already a week behind in this class. More than a little angry.
