You wallet will then also read slightly less because it will get lighter too.

Well, I'm a self-confessed retro-brewer: retro-styles, retro-techniques, retro-grade views on the wild fads of the modern homebrewing culture etc.
An Easyden could be a funny toy to have but you see, it isn't a retro-device, so it won't fit the rest of my retro-equipment, so no, thanks
