If you wear the bag with clip on your belt, you should save it with the safety strap so that they do not dissolve. The safety loop is closed with a pushbutton. And there lies the weak point of the pocket. The pushbutton rips out after some time - I have the bag now for about 45 days, the knob has been opened and closed every day.
Without functioning safety strap the bag is only partly recommendable, despite the low price.
