I don't even turn mine off at night, I usually watch TV in bed and hit my BP about a dozen times in the hour before I goto sleep. I just set it on the nightstand, and fall asleep.
Definately good practice. I do turn mine off before I put it in a pants pocket, as it pocketfired the first time I took it to work, and burned up a carto.
I only goto the office one day a week. If I am not wearing a shirt with a pocket, I will take my Rougstack, which has almost zero chance of firing in my pocket.
