There are some products I've bought that just do not live up to the hype and outlay - so for me, the most expensive combination of under-performers has to be a Cobra Classic, used to remove Mitchell's Wool Fat applied with one of the TSR limited edition brushes. OK MWF is not expensive - but the brush and razor were - and if I could use the razor with any speed without risking severe blood loss, I might be able to finish a shave before the lather disappears.
