I have done some testing with different brushes and never got less than 60 shaves per 125ml. And I load it pretty good.For me it was the towards consumption. XXX lasted 35 shaves, ZiPeppino 38. Now this is subjective on user, how heavy brush loaded etc..without digging out spreadsheet I am pretty consistent on amount loaded, MWF I am on about shave 75 and probably at least 75 more left.
