This warmer is really handy and saves the worry about the temperature, but there are a few things they could improve on: First - you cannot operate this whilst holding a baby! A bit of a problem if you have a screaming hungry baby and are home alone. You have to hold the unit with one hand whilst pushing the buttons - hard.
Secondly - When you need to empty the old water you have to unplug it from the wall and take the unit - plus cable and plug to the sink - a little dangerous. Why don't they keep the cable the same as the one on their steriliser, where you unplug the cable from the unit.
Apart from those two problems the product does make life easier, lets hope Philips read this review and consider these improvements, it will then be worth 5 stars!
