Worst product, even after 12 hours charge it ran for around 2-3 min, maybe they delivered me defected product but its not even worth a penny. Before this one i was using Panasonic Er240 trimmer for last 4-5 years, which is still working and i am using it again. Don't Buy Changeable trimmers, instead buy a trimmer with AA battery option so that you can use it whenever you want as this Phillips one says its charging time is 10 hours? Like More than a mobile phone and powerbank charging time. I don't know what old technology Phillips are using.
