Almost as convenient as the Melitta Ready-Set-Joe manual drip funnel for coffee at work, and much cooler.
Positive Product Points
I've already fallen in love with this gadget -- because that's what it is. It's a spiffy little coffee gadget, and it's both easier to clean and worlds more resilient than a standard press.
Negative Product Points
You have to be careful not to squirt coffee out of the mug with this, and it requires more stirring than a conventional press.
A previous reviewer mentioned he had trouble cleaning the Mug Press. I found the reverse to be true. The "puck" of coffee in the bottom holds together well enough after pressing to be easily dislodged into a trash can. All the parts can then get a quick rinse, and be free of contamination for the next cup. It also comes with a quite sturdy "sleeve" the press can be dropped into pending cleanup, keeping the whole thing nicely self-contained. For full cleaning, a teaspoon or so of washing soda (i.e. Brew Rite) can be dumped in the press with a fill of water, and clean press and sleeve both. Rinsing is all it ever needs as long as you don't let coffee sit in it overnight.
I bought it at Tuesday Morning, a department-store surplus chain, where I've gotten any number of nifty coffee brewers -- presses and mokas -- as well as a good number of interesting demitasses in the past. I've always been quite happy with their service.
