I use Kelly wallet for daily use and it doesn't bother me much to open and close. Half of the time I just turn the turn-lock without putting the straps on but another half of the time I close everything including straps. Most cases my hands are usually idle enough to have plenty of time to put straps on. I'm either walking, sitting on a cab, waiting for food to come out in a restaurant, etc, in all of the cases my hands are free for my Kelly wallet straps!
