great for 15g cups

I like the 02 size better but these are nice for small brews

These are good for small doses

After trying many different drippers, I keep coming back to the V60. I bought a second plastic 01 to do side-by-side comparisons of different brew parameters.

An update to my previous review,
I found the plastic 01 V60 tends to sometimes have a little more brightness in the cup with a light roast coffee, which is nice.
The ceramic version of the 01 is maybe a little more balanced. It might be due to heat retention characteristics I'm not sure, bottom hole sizes are the same I believe.
Plastic has the benefit of being cheaper, not needing a preheat, and more durable (if you drop things), the only downside to plastic really is I'm not sure about whether brewing in plastic is healthy.
