These are great cards. Fast enough to capture 4K video in my drone or my action cam. I trust SanDisk to be reliable. But these were $20 when I was in the club a month ago, and now they're listed at $35?!? What the heck? Glad I bought when I did!

Great for drone video storage

I’m using this in my DJI Phantom 4 drone which has been great for extended video and photo storage. It works perfectly in my USB that takes this unit to transfer files to my computer.

I plugged this chip into my computer and tried to load data into it and my computer locked up, at first I thought it was my computer because it's several years old , I tried to reboot my computer but it was totally locked up. I removed this memory card and everything started working again, I inserted a different card and everything still worked fine , I checked this card to be sure it didn't have any dirt or obvious flaws , it looked fine so thinking it was a fluke I plugged this new card back in and instantly the computer locked up again , I unplugged the card and everything goes back to normal, I've always got good performance from SanDisk storage cards and USB devices but after the way this one locked up my computer I don't think I will use them.

For the price this is the best out there

For the price, this it is absolutely insane. I personally would not go anywhere else unless I see it marked lower. But I would not waste my time, I have spent more and got less GB out there.

Good but not fast

Be careful about speed needs! Looks good but my Go Pro Hero 11 popped a message stating this isn't a fast enough memory card for hi-res videos. Works OK for 1080. Haven't tried it for 4K.

Sam's comes through

It was a great price, I could have it sent to my home and did not have to drive out to the club, and it is free shipping for plus members, how can you beat that

Faulty microSD

The microSD card is not reading and not working. I place another SD card in the adapter, and it showed up. So, something is wrong with this microSD and its faulty.

Works as expected!

Speeds are good and the space is awesome to have. We use this for our Canon EOS 100 camera and it stores the thousands of pictures/videos. We enjoy not having to change our storage very often.
