I did shave with it today and what can I say? It's alright of sorts.
It being a double-edged cartridge you can shave in two directions in one move.
That quickly becomes confusing. I don't mind handleless razors, but this one leaves me cold.
The (probably East-) German blades are not the smoothest.
I have had closer shaves and the alum and aftershave had complaints.
Overall not too bad, but more a curiosity than a revolution.
All in all well worth the money as a prop to practice my 360-degree photo technique.
