Best SD card around
Best card on the market. Highly recommend, especially for my OM 2 slot system
J. Cook –
Bright Color is a plus
I have no way of testing the cards scientically, but they seem as fast or faster than other SD cards. I like the bright color. Since most camera gear is black, gray, or other dark colors, it makes managing the cards in cameras and card holders convenient. Can’t speak to the durability at this point, but they seem sturdy and well constructed. Time will tell.

Works great
One card had damaged packaging. Both cards purchased worked great. Speed was as advertised. Card material is stiffer than average.

Fast write speed
The card is used on my OM1 Camera and the fast write speed has allowed much longer burst rates in continuous mode at 50 fps compared with the Sandisk.

Buffer speed
Did not buy it from Amazon. Bought it from a local photo store and is a big upgrade from the V 30s that you buy from target. Buffer increases significantly even though on the camera it does not say it.
