Negative Positive
Title: Works well, but could use some design improvements
Review: As other state, takes about 15 minutes to warm a full pot to the temperature necessary for making instant coffee or oatmeal. The lid fits well enough to prevent spills if supported in an upright position (wedged into my passenger seat against my luggage), but is by no means water-tight if it happens to tip or get bumped. The adapter does not fit tightly into my cigarette lighter, so I have to keep an eye on it, as it does occasionally pop out. Overall, I'm glad I have it on my 2-month road trip, but it is not convenient enough that I will use in my everyday life when I get home.
Is the review positive or negative?
