and I take 3 pictures and my camera shows a card error, so I put it in another slot and still get the same error.

I started getting memory card errors on my Nikon D750 after taking a couple of hundred photos with this card.

However, the next day the same problem occurred; after taking only a few photos, the card caused a "card error," preventing me from taking any more pictures

No card error problems ever, and we shoot a lot on Canon 5D Mark III and 6D these days and the cards keep up!

Both failed immediately, showing "card error" message, after shooting just a handful of frames with my Nikon D7000 DSLR.

The camera gave me a card error which persisted regardless of which slot the card was in

Its first real test came at a wedding where I noticed my Nikon D810 suddenly giving me a card error

It works as it should....

I've used it on a trip to Scotland as well as to take some photos of product pictures for my website and haven't had any issue with it yet

I appreciate the value for something that works as it should.

Works as it should in my Canon Vixia.
