This is a good shaver. It shaves well, it's a neat form factor, it's small & light and would be ideal to carry if you travel a lot. But it's no better than any other electric shaver I've owned. No worse either. It's just another shaver. The idea that this is 'revolutionary new electric grooming technology' is pure marketing puff.
I'd give it 5 stars for shaving perfectly well, but I'm taking one off for the excessive hype.
