Already by its design, modern and elegant, with its good grip with Gore tex pleasant to the touch, and especially its effectiveness.
What really impressed me in the Waterflex Braun razor is that it suits you and not vice versa: dry shaving, in the shower, with foam or gel, it is quite versatile. Finally a razor that is not responding to a single need, but all my cravings.
Quick charging for a long enough time to use.
Easy cleaning under water after use.
The price is right when you think about it because on my current razor I had to change the blades regularly, something I'd do more with the Waterflex braun.
The only drawbacks is that it lacks a support and a carrying case for my travels.
For now this razor suits me perfectly so I recommend their eyes closed.
