Yup, that is identical (IN form) to the Melita Single Cup #2 cone filter holder I mentioned up-thread. I had one.
I still do coffee cup at a time but these days I use a Proctor Silex one-cup brewer, it too uses #2 cone (or Senseo Pods) and I'm now using fresh ground coffee.
I have two coffee grinders, One is a old Braun with a bad switch so it runs whenever it's plugged in,, I bought a Mr. Coffee to replace it and will now review them both
They are both knife mills (Spinning blade chops the beans to powder)
On the Braun you put the beans in the grinding cup which is attached to the power unit and put the lid (Plastic) on and press the button till it's properly ground, You time it yourself. Shake it a bit to get a more uniform grind..
Then turn it upside down, wack it a couple times with your hand to knock the ground coffee into the lid, lift the power unit off the lid and pour the ground coffee into the filter.
With the MR COFFEE, the grinding chamber can be removed, which makes it easier to clean..
With the grinding chamber in place you select the number of cups and the grind using front panel buttons, You then put the beans in and apply lid, press and hold the button and shake it a bit as it grinds, a Timer shuts it off when it thinks the beans are properly ground.
The grind is the worst grind of any coffee grinder I have ever used, I need to run it at least two cycles to get a decent grind. And the think works when it feels like it, I often have to unplug and re-plug it to get it to work at all.
l highly recommend the Braun. (Which thankfully I've not yet thrown out).
And as for the Soda recommendation: NO, it's easier to heat them up on a campsite. and I dont need all the stuff they put in a soda bottle, Way too much acid, sugar or artifical sweetner, and other chemicals.. Coffee, though also full of chemicals, is all natural.. ... In another forum someone posted most of a joke; I like my coffee like my women.....
I usually order coffee "Straight".
(And by the way that is how I like my Women.. .Straight)
