Philips QT4001/15 beared trimmer, I am using this trimmer for about one year and I got some experience of this trimmer which I am going to share with you. this trimmer is overall good but if you think deeply its not good so, because its price is not so less and in this price you can buy much better trimmers of nova. as everyone think of Philips trimmer comes with lots of features yes its ri8 but not in this trimmer. its trimming and size quality are average. battery life is ok. looks good and its opening sizer, feature is also good. but the only problem I feel there is no more and more size for cutting beared and its not so smooth also but but ok if you are a brand lover else in this price you can also get a better trimmer of different brands.
