I too have the Hourglass and love it! I take the bean kanteen that comes with it to work and all I do is add hot water, it's so affordable and the coffee is awesome. Smooth and always flavorful. I have even gone through the drive though coffee place and ordered just hot water since I have my bean kanteen in the car for coffee on the go.
The Hourglass is so easy to use and clean too. Can't imagine going back to drip or the office sludge again.
