It worked fine at a start and offered great speeds, but after a few months my cell phone started to eject and reconnect it several times per day (at least once per hour).  That made my phone eat up its whole battery life in half the time.  I installed Watchdog and noticed that the Google+ process also incremented its CPU usage.  I read somewhere that it was caused by this kind of problems with microSD cards, probably because the process was trying to scan the memory once inserted.  In another forum there are also reports of this kind of problems with some of the latest generation SanDisk microSD cards.Now I decided to purchase a Samsung one which can be found similarly priced.  My phone stopped acting up, and its battery life came back to normal.
