Very good product although a few improvements could be made.
Firstly, it is quite dangerous and very inconvenient to have to unplug the whole unit in order to empty the used water into the sink before measuring and re-filling the unit with the correct amount of water for the next use. It would be much better if there was a connector to the unit which could be pulled out so that the plug and wire does not have to be taken to the sink with the unit.
Secondly, the cord on the plug is not very long, this could definitely do with another few inches on it.
Thirdly (and lastly) the buttons on the unit are quite hard to press (and you have to press and hold the buttons to start it), you cannot press the buttons when holding anything (including a baby) as you have to hold the unit with one hand and press the buttons hard with the other.
Regardless of the above imperfections, the product is great and I would not be without it. It warms the milk to the correct temperature and does it quickly. It also warms milk from room temperature, fridge temp and from frozen so there are plenty of settings and uses for it.
