Sunshine Kids Warm N Go Insulated Travel Bottle Warmer, Royal Blue
Price : $ 10.99
This travel bottle warmer has good design. The differences with other it has no buttons in the bottom that would turn off when the bottle was not directly on the sensor. since the others had oval bottoms they didn't fit in a standard cup holder either, thus it had to sit on it's side and the bottle would move off the sensor and it would turn off. this one stays on , heats quickly, and fits in cup holder.
