Philips QT4011/15 Pro Skin Advance Trimmer is so advanced as product name says. It is little bit costly but it really worth’s your money if you purchase it. It is easy to use and it fits your palm very well so that it avoids chance of making marks on face. It has long battery back up. It effectively removes your hair with no skin scratches and all it goes deeper and removes hair. As Philips is a good brand it’s product usually has long life. You can purchase it. So my overall review about Philips trimmer is "Best".
