Review on Amplim Extreme High Speed 512GB Micro SD Card - MicroSDXC U3 Class 10 V30 📸 UHS-I TF with Adapter: Ideal for Nintendo Switch, GoPro Hero, Surface, Galaxy Phone, Camera Security, Tablet by Gabriel Tomato

I gave this device one star for its rating and value. The reason is that it was an expensive card. He was super fast too. I bought it for my Go-Pro 8 and a trip to Alaska. I recorded about 2 hours of video, photos, 4k videos, flashes, etc. Everything looked fine. The last video I shot was at the airport leaving Alaska. No problem, right. I come home, turn on the camera and it shows a map error. You have to format the card to recover it, but you will lose all your data. There really are no words to describe it. In the future I will not buy such expensive crappy cards, nor will I ever buy from this seller again.
