Very glad I wasn't on an actual shoot, card writes very slow.

I wasted $100 on a fake SD card

This is supposed to be a good SD card

Card I got sent is a knock off

Perhaps it is a corrupted or fake card

The card is great with the read/write speed as specified

Expensive little card, but the write speed is wonderful

Be careful."Legit" card (on left) versus "Fake" on the right

And most of all, when I put it in my camera, it can't keep up on continuous shooting the way the authentic cards do

Both cards failed within days of first use

Either this is a fake, or bad card

Possible fraudulent card

I tried upgrading to a faster card and this one is a fake item.

I'm using it with my Nikon D850 as secondary card and woeks just fine!

These cards are fake, yellow tab, no serial numbers, do not use or buy, just a hassle, returning now

This card does not always work, even when you think it does

These U3 cards DO WORK for 4K footage with the Canon 5DIV.

Slider on the side was a different color, no serial number on the card, color on the front is different than authentic cards
