Built to last. Brews directly into your cup.  Primarily a pod machine, but accepts freshly ground coffee as well.  Also contains a tea making attachment.

Brews weak coffee with no ability to effectively adjust the brew strength.

I have used this one cup coffee maker from time to time for about a year since I purchased one for a colleague.  My office subsequently acquired another.

Touted as an easy-use single cup brew system, I unfortunately cannot think of a reason to recommend this product.  Its convenience cannot overcome its brewing shotcomings.  First, it is only slightly easier to use than a regular drip coffee maker.  The only steps that are removed from the coffee making process are measuring the grounds (if you use the pods) and cleaning the carafe.  Also, the Melita One:One (MES-1) isn't small - it takes up about the same amount of space as a 10 or 12 cup brewer.  (See Coffee Geek Quick Shot Review of the Black & Decker Brew N Go for a more compact and much cheaper single cup maker that apparently makes decent coffee).

The main weakness of this coffee maker is that it brews very weak coffee.  To brew,  you insert a pod or pack ground coffee into the unit's steel basket and snap the top down. You can select a small or large cup setting, which regulates the volume of water to be sent through the grounds.  However, for those who enjoy a robust cup, even the Melita dark roast pod set for a small cup produces dull and weak coffee.  It's as if any intense and distinct flavor notes in the beans are muted by this machine.  I have also tried brewing freshly ground coffee and even tried increasing the volume of grounds by tamping them down hard to no noticable effect. Perhaps this product would function better if the pods and basket were made larger.  

As for the construction of the MES-1 - it has a quality feel.  The stainless steel drip tray and pod basket (which resembles an espresso portafilter) look especially good.  I purchased the MES-1 as a gift based on the outer quality and Melita name.   I wanted to make it work well, but couldn't.  In the end my collegue purchased a low-end 4 cup brewer and is far more satisfied with the results.   Another colleague of mine, however, does like the MES-1.  He generally prefers light bodied coffee, yet w/o a great amount of brightness.  If you like that taste (and I do have some relatives who do), this machine might satisfy you.  

Final flavor note:  The MES-1 will make any coffee that you put into it taste like Folgers (yes, even stuff from Aurora and Intelligentsia).  That said, there are plenty of people who buy Folgers, though they probably do not visit this site.

Uneventful - purchased when it was rather new to the market.  I have now seen this product for about $10 less.
