Spring has sprung here so yesterday I cycled all the batteries for my MPP, FC, and CS.  I also did the Go 4 update for the CS and the firmware update for the MPP.
I did all the updates via wifi and they downloaded and installed flawlessly.  Go 4 update on the CS was quick.  Firmware update for the MPP done with wifi through the CS only took about 25 minutes.  
My CS (5.5") has always worked great and has yet to let me down after a year of use.
