This is a great, cheap way to get into vac coffee making.
Negative Product Points
I have yet to get a stall from the disk although I can see how it might happen. But really, the disk is a stroke of genius - even if problematic. My only complaint is the handle - I'd prefer a screw tightened-band as in their Chambord press pots.
Its my first vac pot and it works great. I've tried several types of grinds and find that its very forgiving of the size of the grains.
As for taste: I had a lb. of Kenya Peaberry that I really didn't like. I was ready to throw it out but decided to try it in the vac pot first. It really did well in this thing. I'm inclined to use this thing whenever time or volume permits.
As for useability: Don't make less than 16 oz. in this thing. Preferrably 20oz. or more. I tried several amounts as experiments - definately works better with more water. If you want a vac maker that will do less volume, get a smaller one such as the Cona or Hario or even the Yama.
