Great vintage item that makes great coffee! Easy to remove top globe. No worn out gaskets to worry about!

You have to be diligent to make sure that you get a good seal on the glass parts since there is no gasket.

LIKES:
Contrary to what others have posted I love this vacuum pot. I have only once had a stall where the vacuum was broken and the coffee failed to be pulled down into the bottom globe. I've since had probably 75 no problem pots of coffee. The method I use is to get the water in the bottom globe heating. When I start seeing vapor wisps and slight bubbling I know it is time. I then turn on the faucet in the sink and getting my finger wet I run it along the top seal of the bottom pot. I make sure that there is a good film of water here. You have to be careful to make sure you don't get any water dripping down the side or pot explosion could happen! I keep wetting my finger under the faucet and do the same to the bottom seal on the upper pot. When both ground glass seals are fully wet I place the top globe onto the bottom and watch the brew process. When it's done syphoning into the bottom the top lifts off easily. No wresting with tight gaskets, etc. I think this is the part that I like the best. Some of my other vacuum makers get stuck on the bottom pretty well. I have used a new Cory rod as well as the old style Cory rod and both work very well in this pot.  

The Stove. These are very hard to find. Mine came new in the original box. I scored a good deal on this from Ebay. Make sure if you get a stove that it comes with the original cord because a standard applicance cord or a cord from another pot will not work. The spacing on the prongs is different. This stove besides looking really cool heats well and has a keep warm feature (see below).

DISLIKES:
The Handle. I switched out the handle on this pot with one from another Cory pot. The handle that comes originally with this pot is very small and hard to hold with a full pot of coffee up top. I also dislike the metal band which holds the handle to the bottom pot. It is aluminum and as such is very dull. It doesn't match the shiny chrome stove or the two gold bands around the pot. I wish this band was a nice stainless steel.

The Stove. I have the original Cory stove for this and I have a love/hate with this. There is a heating position and a keep warm position on this stove. To use this you must unplug the cord from the side of the stove, flip a metal flap over and reinsert the cord. It's a really weird setup. Basically there are three prongs on the side of the stove rather than two. Well after you have made the coffee this stove is HOT. It is almost impossible to unplug then replug without burning yourself.

Great buying experience on Ebay. The seller packed it well and it even came with the original instructions.
