The verdict of my husband was very fast: he loves. He has a difficult beards and shave was always a chore. He had been seduced by a competitor, Braun and there is nothing he will not abandon the three heads.
Shaving is very quiet, very comfortable, handy and it leaves the skin soft.
The fact that it is completely tight especially is very reassuring for the cleaning and the fact it can be used with shaving cream.
Digital load meters are also a good point and can anticipate. (No razor may be used on AC power).
Cleaning is based on a real luxury. The cassettes are cheap (30 euros for 5 to 15 months)
Two negatives:
shaving under the nose is not very convenient to share the head size
the significant size of the base that occupies the lot bathroom vanity and the fact that it must be plugged straight 4h for cleaning and drying.
