Genuine but somewhat slow - not for Pro use or burst mode.

I would not recommend this card for anyone with a very high Megapixel camera.
30MB/second is not very fast. I'm not great at math, but this is a pretty simple problem:
A Nikon D800 has a 36 megapixel sensor and RAW files coming out of that camera can be around 50MB.
Writing a 36 MP photo that is 50 MB being written to a 30MB/sec card will take almost two seconds to write to this card. And that is under IDEAL conditions.
Now consider that you are taking 10 photos in a row in succession (such as with a burst mode. It will take you potentially 1/250 or 1/500 of a second or however fast your shutter speed is (plus lag) for the shutter to open and close and capture each photo.
BUT the photos then need to be added to the camera buffer and written to the card.
So, assuming the buffer of your camera can actually hold all 10 or 20 or 30 photos you took in burst mode, the camera needs to write them to the card and you will be waiting to use the camera in the meantime.
If, for example, you took 20 photos in burst mode and are capturing in RAW format, that's going to be 1000MB you need to write at 30MB/second.
In this example with a card of this speed, you will be waiting around __33 seconds__ until you can use your camera again!
That being said, for high megapixel cameras, you are going to be much better off with a faster card. If you can double the speed of the card, or even increase it by 50%, you are going to be writing faster and saving files faster and therefore able to using your camera for more shots faster.
But, for standard point and shoot users, who are taking a single photo at a time, this card should be fine.
JUST REMEMBER: You do not want to store ALL of your photos on one card ever. Make sure to change cards frequently (before they fill up) because if the one card you are using fries or dies, you will lose all of your photos.
