Does anybody use a shutdown button for their RPi?

Just wondering if anybody had problems with the SD card getting corrupted.

I once had a corrupted SD card after unplugging the lipo from my rover. Emlid told me to use a slower SD card (class 4 instead of 10), because they should be more robust. I use them in all my Rpis now and never had a problem with a corrupted SD card again.

Thanks, I will try that.
