The unit has together form a trunk and a head which quite a long incline. In between, the blade is placed so skillfully that it is flush with two parts - it protrudes no blade out. At level 1, the injury risk is not higher than with a system shaver, what surprised me very much. Stage 2 is also harmless, with Level 3 you have to start only ever watch. What stage 5 is I do not know, maybe a 5 year to remove Bart :)
I personally use level 3 for cheeks + neck and level 1 for the oral cavity.
As for hygiene, who uses razor system knows sure versiffen the blades.
When planing the gap dimensions of the blade are great hair flutschen easily under the blade in a huge cavity in the fit a complete three days beard. Just held under water and the unit is as clean as before shaving! No hair can stall.
The Wilkison has neither this long incline prevented compared to the cuts, even wash the cavity for.
The Price. Well at first glance look 55 look like much. Considering the 100 Astra blades 12 costs and this razor was made for a lifetime, then you have 5 years warranty with 500 more in the account than with the use of system razors. A better shave than with the device here gets out only the professional with a razor.
