1. The razor blade is mounted in an articulated way to the hilt. However, the spring is the sword holds too hard for me. You have to press the blade rather firmly to the skin, so that the spring yields. Therefore, the handle can be not so nice and light on the skin as the Mach 3 Turbo result, here the spring is much smoother.
2. The individual blades are rigidly mounted in the razor. At Mach 3 Turbo, the 3 individual blades are mounted in each case flexible, so they give in to pressure. This has the effect that the blades when ShaveLab Fire as a great board walk through the skin and small bumps are not compensated.
3. The handle of the razor is very thin and long. Because he is so thin, it's hard to take him. I then held the razor very close to the blade, which went reasonably. But then sometimes the handle is in the way, as you can well lead to a greater angle than the skin him for point 1 not.
These points lead me to which I have already repeatedly cut myself uncomfortable with the ShaveLab and the skin is irritated after shaving. I also have the impression that the shave is not as thorough as with the Gillette.
The shaver is certainly not bad, but in direct comparison I see him as a loser. I'll probably use up the 4 supplied razor yet, but I will not order new.
