I have enough memory to move over many things that was slowing my phone performance and know my apps and pics, video, etc. Work really well.

Worked as intended for my camera Sandisk is the top of the line

GoPro 9 Hero Black

So far so good from Amazon, these ones appeared legit and have worked very well so far. I use them for my GoPro and have not had an issue as of yet. I have more issues with my GoPro though. But thats not the cards fault its GoPro. If you own one you know what Im talking about. Well take care everyone
