Amazon is getting more than 4 orders from Dash Buttons a minute

""Just a year ago, orders via Dash Button were occurring more than once a minute, now that rate has increased to more than 4x a minute," Amazon said a statement. For some items, like Folgers coffee grounds and Glad garbage bags, Amazon says "more than half" of their orders are made via Dash Button."
