How long does one bottle last?
Using 2-3 pumps once a day, how long will one bottle last? I have had this product for 3 weeeks and have only been using every other night and it seems as if it is either already empty or has a malfunctioning pump. Similar products with the same volume have lasted me many months using once every evening. Complete waste of money if this is it!
