I'll be honest and say I thought this product was solving a problem I didn't have, I'm usually an espresso machine coffee drinker but my local roaster recommended I try it and now I hardly use my espresso machine. Not just great for one cup (which it is) but also seems to keep the coffee hot for quite a while before pouring, I let mine brew for 20 minutes or so, one and a half table spoons of ground coffee ground for a cafetiere and it's just perfect. It's re-ignited my love of enjoying a great cup of coffee and enjoying the making of it as well.
