The percolator tube is really small in diameter, only 3/16" The grounds tray is too small to put in enough grounds to make 50 cups of coffee. The spigot doesn't flow coffee through. The pot is tall and narrow. It is on its second brew now and the light keeps going off and on. It re-perks every 7 minutes.Update The spigot handle broke off after 5 weeks of use. Amazon won't back it, neither will square trade and the manufacturer requires I pay postage. What an all around amoral sale by amazon, square trade and better chef. Now I lost over $50 and am left with a piece of junk.
