I realized that showering with it is pointless. When water gets on the screen you can't even use it anyway. The pebble was more useful in the shower. I was also worried about getting it too wet. I realized it also pointless to wear in the car, I almost got in three accidents looking at my watch while driving. So I think shower and driving is a perfect time to charge it. When ever it takes my heartbeat I can feel it and it hurts. It hurts my wrist and I often feel pain in my wrist even when I have the watch off, which has me wondering if I should turn off the feature that periodically checks your heartbeat.
