Cons: sadly i made a blunder, i misread the description and thought that this was a micro sd card, which is what i need for my phone. unfortunately it is not a micro sd card and i do not have anything that i can use this in. and for my mistake i will only take 1 egg away because it isn't their fault.
Pros: Super fast with my Nikon D90 takes and stores pictures/videos super fast. also downloads to my computer with a very decent speed. Fully compatible with my camera, multimedia player and computers.
Summary: Bought this for use in my RasPi model B for RetroPi with EmulationStation. Works great! Copied all my Roms to it at about 12MB/sec, using my work HP Elitebook using the built in SD reader. Did that wrong, but also wrote the image file at about 11-12MB/sec. Have not done read tests.
Pros: Was cheap-ish... Went on sale the week after i bought it.. ACK! Class 10. Fairly large, more than i need for my Pi that is.
