Nicely integrated product that is well though out. The burner wick is a loop of metal that vaporizes the alcohol before it burns - an ingenious design and no cloth wick is required.
Negative Product Points
A bit small in volume. Listed as 5 cups (on the side of the bottom carafe) but at only about 20 ounces, it really is only adequate for two or three cups.
Has paper filters that really produce a sediment free cup. A spring chain holds the filter in place very well. I preheat the water in a microwave to almost boiling to save some time since the amount of heat from the burner is relatively small and would take a while to heat 20 ounces to near boiling. My first vacuum coffee maker and I am sold on it.
