Looks like right under 3 months per puck of Williams. 5-6 shaves per week (minus 5 days in Dec when I couldn't shave). Today is Jan 15, 2018. I started this puck on Oct 24, 2017 Edit - I don't lather as much as others do. If you lather this to "canned foam" consistency, it won't last as long. My lather is whipped for only about 30 seconds - more of a thick, soapy film than lather. But it works well for my face.
A puck will last me about a month if I use it daily. Clayton Sent from my SAMSUNG-SGH-I337 using Tapatalk
That seems right. Williams pucks are 1.75 ounces and you can generally get 10-15 shaves per ounce, depending on heavy or miserly loading.
And I load it heavy, I find I get the best lather when I do that plus add 2 teaspoons of water to my lather bowl. Clayton Sent from my SAMSUNG-SGH-I337 using Tapatalk
