Very nice unit that includes in shavers, trimmers and hence a weight saving when traveling. But: The extendable trimmer is not particularly durable. With me, he gave up after one or two years at the latest. Then the device shaved still, but the trimmer is and gets caught in your hair - painful .... So: Who uses the device much need after 1-2 years a new. I know what I'm talking, I've been the 5 device because I travel a lot and the competition has nothing comparable. So why the product improve ;-)
