The blades and the ultra thin foils are hypoallergenic which ensures smooth and gentle shaving for sensitive skin. In addition, the blades are angled at 30 degrees relative to the face which is considered the best angle for a clean cut.
Pro Universal voltage makes it convenient for traveling
The available voltage for the charger is 100 to 240 volts which makes traveling easier by not having to worry about any additional appliances.
Pro Cleaning is straightforward
Performing a basic cleaning is easy. Rinse the shaver under a tap while activating the sonic vibration cleaning mode. This will remove any hair or gel that was stuck to its blades or foils.
Pro Dry and wet usage
The shaver is completely waterproof and can shave dry as well as with a gel or foam.
Pro Fluid movement
The combination of a pivoting head and the two-motor system gives an extra fluid movement while shaving. The pivoting head will automatically adjust to the face’s contours while the two motors create vibrations to move the shaver up or down and side to side. It isn’t limited so much in movement which creates a rotary shaver feel.
Pro Cleaning is simple
You'll not have to spend a lot of time cleaning the shaver's cutters because the S9721/84 comes with an automatic cleaning station.
Pro Good for sensitive skin
This electric shaver is ideal for those with sensitive skin because its rotary design prevents the cutters from getting too close to the skin. In general, the rotary shavers are known to be good foil shaver alternatives for people with sensitive skin.
Cons
Con Can have difficulty at harder to reach places
Some places might be more difficult to reach because of the larger head. Small angled sections, such as under the nose or under the neck near the ear, can be tough to thoroughly shave.
Con Expensive consumables
Replacing the shaver's head will cost you a pretty penny since. On average those heads cost around 50 dollars.
