Effective bottle warmer for home but it takes longer than expected in the car.

Very nice bottle warmer. Simply remove the blue portion is graded to pour the required amount of water. (A table shows the amounts of the bottle).
It comes with the outlet to plug it into the cigarette lighter of the car. I tested it in the car, it took 20 minutes to heat a large bottle (instead of 6 minutes 30 shown).
At home it heats a bottle of 240 ml in 2 minutes, for cons there is no ringing to warn that the bottle is ready ... It is known as the indicator light off (and the water in the tank s has evaporated).
The plus is that the bottle is really at the right temperature and keep it warm if left a few minutes in the bottle warmer. It can also warm up the small pots.
Very good product, it would have been perfect with a beep and more.
