Uninsulated brewing chamber (like most auto-drips), barely adequate coffee temperature (without hacking the unit), flanges make cleaning more of a hassle than it needs to be
We bought the glass carafe version of the 741 at Williams-Sonoma several months ago, and as auto-drips go this one is well above average in build quality and performance. We were amazed at how much quieter it is than our previous (still concurrent) unit (a Zojirushi), but less than wowed by the difference in coffee temperature. Although the Zoji is a thermal carafe model, its brewing chamber is better insulated, and with carafe preheating it actually produces hotter coffee ( at least for the first hour) than the hotplated Moccamaster. This was a disappointment since we avoided thermal carafe models this time around specifically because we prefer coffee that's actually hot instead of moderately warm, and was hoping a hotplate would give us a boost in temps. It didn't.
Which leads to my first gripe about the 741. I don't care what manufacturers or reviewers might claim, the rubber gaskets used in most autodrip baskets impart a distinct and nasty quality to coffee, and unfortunately our Technivorm has one. Or rather it had one. We yanked it and the clip that connects it to the slide switch on the brew basket, since we never use or need the pause or half-pot settings anyway. The change resulted in major improvements in both coffee taste and temperature, although I'd still rate the latter as barely ok.
Another design decision that I question is the Moccamaster's use of flanges, on nearly every part (the water tank lid, spray arm, carafe handle etc). I'm trying to understand how they couldn't know that thin flanges equate to extreme splashing when trying to clean parts under running water. Usually directly back in your face or all over your shirt. Just a ridiculous lack of thought by Technivorm's designers imo.
Other than that we're happy with it, and will probably keep it as long as it runs. The copper heating element really does make a major taste difference over aluminum.
