I've only been using this product about twice a day for a couple weeks, so I can't speak to its longevity in craftmanship.  Aside from the travel mug, all parts appear to be very light-weight plastic.  I'll be sure to amend my comments, if I have any problems down the road.  It's been a decent little coffee maker so far and much handier than our 10-12 cup pot, when making coffee just for myself.  I just wanted to chime in with a couple early observations some prospective buyers might be interested in:

While it does hold a full 15 ounces, as advertised, this is the smallest travel mug I've seen, personally.  I've got dozens of travel mugs and none are short enough to be substituted in its place.  Nor will your typical, but taller ceramic coffee mugs or paper cups fit in the machine.  Not that either is a deal breaker, I just expected something that would work for a larger variety of the containers I commonly drink coffee from, short and tall; that's one of the reasons I opted for this unit over the less expensive short mug models, and I feel it's a design oversight of Black & Decker, not accomodating taller containers in what is essentially a 2-cup design.  It's not that I wouldn't still choose this model over the even shorter single cup versions again, but just another 1/2 inch would have made this unit so much more versatile and useful.  I'm just saying... It's not like taller coffee mugs are at all uncommon; they've virtually become the norm.

My only other criticism is with the permanent filter letting through some of the grinds.  It's not a lot, but it's enough to disway you from taking that last sip or two.  I find it still necessary to use paper filters, which likely will need to be cut down from a larger size, unless your nearest grocery has a deeper selection of filter sizes than mine.

As for the coffee itself, I find the manufacturer's 2.5 tbsp recommendation to be the minimum ratio for the accompanying mug.  Even using freshly ground beans, only 2 tbsp per 15 ounce mug produced a weak and rather bitter result.  I think I've settled on 3 tbsp per 15 ounce serving.  It's a bit strong for my taste, but there's no trace of bitterness and it's better to weaken coffee by adding more water after percolating, rather than using less grind or more water prior to percolating.

Regarding how hot this machine heats the water:  I honestly, don't know how anyone could drink their coffee any hotter than this, and, with the lid on, the travel mug traps the heat very well, as you'd expect.  I usually add some cold water, if I want to weaken the coffee, or a few ice cubes, if I don't, just so I can begin drinking sooner.  I'm not one who likes my coffee scalding, but if I were, this machine seems capable of making coffee just that hot - hot enough to burn my tongue anyway.

Update:

After using this coffee maker once per day, every day, for five months now, it's still going strong.  However, as others have reported, the mug has begun to leak a bit.  It doesn't leak the coffee, rather, it seems that water is somehow getting in between the plastic liner and the outer metal shell - either from condensation or when washed - and it's become tricky to take that last sip or two without a little water dripping down your chin.  A narrow bead of glue, just below the plastic rim, where it lips over the metal, will probably fix it; but I just discovered the problem and haven't done so yet, as, if it's trapped dish-water, rather than condensation, draining the mug on it's side, will probably work too.
