"performed as advertised."
That Crazy Photographer
Being a photographer i chose my memory cards carefully. This product is good. This is my third memory card from strontium. And they've all been excellent. It gets delivered with an sd card adapter and a usb adapter which are both really useful and other big brands like sandisk, transcend, etc don't provide you with both. They just give an sd card adapter that too not with every card.
I used this card with nikon d800e and it worked well. That should tell you that the speed is as advertised. It didn't deliver results as good as the strontium nitro plus, but that's just because the nitro plus is a faster card.
On my phone, it performed flawlessly.
If you're looking to expand the storage of your phone, tablet, digicam or even a dslr like 5d mark iii, thus card will deliver the goods.
Had issues with delivery but the card is good.
