I got one as a gift. I use a perk on the stove with hard water here in my hermit cave. Mr Coffee gets clogged up.
Now I buy fancy water in a plastic jug to go with expensive coffee in tiny plastic jugs to pour in my high priced small cup making electrical machine.
And I use it once or twice a day after firing up the stoveperc. But I like the merlitti? recommendation.
I forgot to mention that my mom and dad LUV it, especially my mom. I luv donut shop and one or two others but I must be accustomed to the taste of stovetop.
