When we first received it and used it, it made a loud humming sound when on

No one had mentioned that while the unit is running (which is constantly in order to keep the coffee hot), there is a very quiet hissing sound of the water/coffee being kept warm

I love it because the coffee stays hot, takes up less room,wish it had a louder sound when it is ready

This is the older model and I have heard the new model does not make the sounds while staying warm.

I can live with the percolating sounds while its brewing but the noisy warming boiling sound of "keep warm" makes me anxious

So far this one is being used regularly, it does make a fair bit of noise when it's in warming mode, little hissing noises with bubbles sound (like a kettle that just near boil but not quite)

No one had mentioned that while the unit is running (which is constantly in order to keep the coffee hot), there is a very quiet hissing sound of the water/coffee being kept warm

Although it stopped the leaking it makes a horrible sound like broken ball bearings ,or rocks rattling around in an empty coffee can, and it takes forever to complete it's brewing cycle, and with the cleaning light blinking

And if you want a more robust cup o' joe, you can press the brew strength button for BOLD before brewing.

I love it over our old cheap-o from Walmart
