Originally I wanted a two cup volume, so I was a bit apprehensive when I got this Hot Pot, as it holds a quart. But I quickly discovered the larger heating element at the bottom heats my water for my morning tea faster than my smaller one did. And it has the versatility of being big enough for cooking more things. Its very light-weight. It saves on energy too, using 110 and bringing two cups of water to a boil in three minutes.It does not shut off once it reaches boiling. You have to unplug it. But I installed an on-off toggle switch at the outlet, which the Hot Pot plugs into, so I just hit the toggle switch to shut it off rather than unplugging the Hot Pot. The switches are readily available at hardware stores and are inexpensive.I would still prefer a smaller one for travel, but this actually isnt all that less convenient to pack: just stuff a shirt inside it.
