I am using this product from 7-8 months, it’s easy to use and trim smoothly.battery back up is much better than other and if you charge one you can use 3-4 times.And it have a 20 adustable size which give a better look.Adapter cable’s length is best and adapter’s light indicates that you trimmer is charging or not.It’s blade is good, remove easily and clean it easily.this is the awesome product of philips and everyone can buy this without any hesitation.
