Nice compact size but a little smaller than I thought.  Can only hold about one 16 oz bottle of water or maybe two or three of those half size bottles.  I like the fact that it has a regular and a car plug so you can use it while traveling.  It says to wait 24 hours after delivery before plugging it in for some temperature control reason so I don't know how it is in terms of temperature yet.    Could come in handy in avoiding a trip downstairs late at night to get a cold drink of water.
