High quality construction that has lasted 70+ years so far. Makes a great cup of coffee when it doesn't stall. Very cool way to get full extraction with all of the oils and flavors. Brewing temperature is consistently between 198 and 202 degrees F.
Negative Product Points
Very particular about the grind; must use coarse grind with glass rod filter. I also have the Fast-Flo cloth filter which works much better and doesn't stall the vacuum process.
Detailed Commentary
I purchased the Cory Vac Pot based on several reviews I had seen on several websites and found it very interesting. It's a great piece of history and still makes a great cup of coffee when it works properly. The problem I have had even with coarse grounds, is that the vacuum process stalls due to the glass rod filter becoming clogged. I also have the Fast-Flo filter which is a cloth filter that is held down by a ceramic weight. This works much better as it does not clog up and I'm able to keep the brewing time to 4 minutes.
I also have a new Yama Vac Pot which uses a cloth filter that is held in place by a disk which is secured to the upper pot by a spring that attaches to the bottom of the tube. I like this one too and both have their pros and cons.
The Cory has a wider mouth on the lower pot which makes it easier to clean. I can barely get 2 fingers in the Yama. The Yama has a more sturdy handle that feels much more comfortable when holding. The Yama is new while the Cory is a piece of real American history.
Buying Experience
I bought the Cory off of E-Bay. No problems were experienced and the price was $30.00 including shipping.
