i love this mug. i fell in love with williams soap, and after using it for awhile in a regular coffee mug, i happened across this on ebay. works great, holds my puck still so i can lather on top of it. it doesn't fit down in completely, but it holds the puck snug and you can lather just fine on it. it was a bit pricier than i expected to pay for a mug, but after figuring out i never need to buy another shave mug again, its pretty darn good.
