Query: Warms bottle in MINUTES is TOO vague!

I recall the packaging saying it could take up to 15 minutes, but when my husband and I go on long car rides, we have to anticpate our daughters hunger at least 45 minutes in advance to get the bottle to a temperature where she'll actually eat it! It says not to leave it plugged in too long as well, and I wonder if we're using it for "too long" to get the bottle to the heat that it needs to be at! I wouldn't recommend this product, but see it as a necissary evil for long car trips, just so the bottle can be warmed without having to pull into a gas station that may have a microwave! (Those can sometimes be scarier than waiting FOREVER until the bottle gets warm!)
