To my type:
Little facial hair, all colors (yes, everything: gray, blond, red, brown and black has always been so, down to the gray of course.), Shave just 1 to 2 times per week.
Now Zun current Series 5:
To make a long story short, he does not really have disadvantages. It fits perfectly in your hand and delivers perfect results: Absolutely smooth and no irritation or even sores. The nod of the head is flat for Scheer important. That there until Series 5 and which can be paid (ie there was a certain disadvantage) Brown accordingly.
It all models of the Series 5 are mechanically the same way, and the display is the only differentiation. All make the same in the end, because even the cheapest Varinte may indicate a low battery condition - no idea who needs the senseless More information of the more expensive variants.
Another thing for cleaning system:
Since I shave not daily, the cleaning system comes after every shave for use. Its liquid evaporates anyway over time, which is why a rare use of the system is not efficient and therefore not useful. The result hereby is also very good, the extra cost at the site so is fine.
Conclusion: expensive but good! Would I buy again.
