Micro SD cards for DSLRs?

Can you use a Micro SD card class 10 with adapter in a Nikon 7D or Canon 60D?
I found a cheap one in Amazone and was wondering if it will effect shutter speed and performance?

There are lots of fake ones around, especially San Disk, slow cards re-badged as fast San Disk cards.

Amazon in no guarantee as they are increasingly just a middleman between you and the final vendor. Not much better than eBay - sadly.

A Class 10 card won't alter shutter speed, that's determined by the light level available and your other settings (aperture and ISO), what it might improve is buffer time, your camera may take more frames at high frame rate in continuous shooting mode as it should empty the memory buffer quicker, but only if the Canon processor is fast enough to make use the speed difference, a figure that Canon do not tell.

It may speed up transferring your images to your computer, but, again, only if your system is fast enough (USB 3 for instance). Increases in speed need all the links in the chain to be able to keep up.

A couple of "cheap" Sandisks i got of Amazon just didn't work. I then tried dabs.com (uk) which was recommended to me by my computer scientist brother and got a good deal on several Sandisk class 10 32gb size sd cards.
