Wow this is the best trimmer I have ever used. I used many brands but this is the best among them.Good thing is that you can adjust the trimmer cap even for o.5mm. Battery life is also good of 45 mins. I think it is the best cordless trimmer in this price segment. It has 2 years of guarantee.and you will get 1 year of additional guarentee, by registering in philips web site
