Unilever Radox 750ml Bodywash

Radox 750ml with pump is the most useless body wash I have bought,I have been using Radox for years,nobody did any research as to whether the pump actually works in the 750ml container that stands up vertically You just cannot get enough liquid out with pumping 5 or 6 times,don’t these multinationals test these products before putting them on the market?
