"Wonderful tech"

Not much to say other than it is as advertised and it works. I haven't the means to gauge the transfer speeds but I've experienced no lags or delays with the combination of this storage and my hardware (Galaxy Note II).The shipping was faster than anything I received recently.

"It works as expected"

It works as expected. I use one of these on my Samsung Galaxy S4 and another on my Asus Transformer. No problems so far.
