"Great card"

Has held data and transferred with my PC seamlessly. So far no problems with corruption in 6 months. Apps move from the phone to SD card very quickly.

"Expensive but fast"

This is a great speed card.More than 20 MB/sec. Works perfect on my Android device Samsung Galaxy SII (GT-I9100). Also works perfect using CyanongenMod 10.1.The only downside: the price. Is an expensive card.I use it for music playback, like PowerAmp, Spotify and Rdio. Works flawless.
