I was afraid of having hurt the most sensitive areas such as underarms and bikini and after trying it, I discovered a shave without pain!
It just glides over my skin, regardless of the length of the hair, I did not feel anything! No skin pulled or torn hair, nothing, just the sweetness.
However, it is somewhat less effective in the legs, and I mean "less effective" the fact that we must occasionally board several times over the same area to leave no hair.
Regarding autonomy, I received there three weeks / one month and I have not had to change the pils which were provided (and yes, I shave frequently ^^)
In conclusion, if you want a shave without pain, you just found it!
