Philips is a branded and reputed company but it’s product Qt4001 isn’t. The trimmer take a lot of time in charging minimum requirement is 14 hours. The charger is of worst quality it melted after 3 usage. It is not at all user friendly. The trimmer comes with adjustment but they are minor. Once the product is gone it can’t be repaired you have to change it. The service of this company is worst. It is not at all worth of money.No effectiveness .One should go for Nova trimmers .Dont ever buy Philips trimmer.
