[This review was collected as part of a promotion.] I have a very thick hair/beard, i was a bit apprehensive to try a new pair of clippers but im glad i took a chance, this clipper charges really quickly and very light and easy to use with a good range of clipper setting for different cuts, I did not think a cordless pair of hair clippers would do such a good job but how was I was wrong, these clippers are absolutely brilliant. The clippers cut very evenly, the double sharpened blades seem to cut down the time taken to trim my hair. There’s no maintenance needed as the blades sharpen themselves, all you have to do is wash the blades after use. The 5000 series trimmer is great, easy and fast to use and maintain. I would strongly recommend it.
