I bought this the day it came out for the great price of $119.99 and it finally showed up a month later. (I knew this going in). I put it in my Galaxy note 3 and it instantly recognized it and I was set.Speeds in my laptop via the included adapter ranged from 15-30mb read speed and about 12mb write speed. I copied an entire 64 GB card over to this one, and it took some time, but now I have double the space.
