Part of their consideration was the size of the reservoir. I use a Melitta v-cone Cuisinart in the AM, and an Aeropress for the last cup of the day.
I’m cheap. . and I only have one 8 oz. cup a day. I just
sip on it all day; reheat it in the microwave. - When I
first started making instant coffee; the kind I was using
was insipid as swamp water. (Some organic brand or other
& Taster’s Choice, then another brand.) Settled on NESCAFE
hearty brew. None of it is “perfect”; but it’s okay.
