Some people just wear it 24/7, even during sleep.
I had the split after about 4 months (wearing it 24/7, even during sleep), and before that I also could not imagine how this thing would split, and what the heck people were doing with their bands to get it split. Until, of course, my own device broke. I saw it coming for quite some time, after noticing white stripes at both sides of the screen, that were a little pointy/rough. After a while, that was the exact spot the tear appeared.
