Regarding Lentretien, removal of blades is very easy and allows a simple washing with warm water. According to Philips, the Smartclean system to use on a monthly basis, allowing a further blade cleaning. I not nutilise shaver long enough to judge the usefulness of this technology (somewhat time consuming, however, when it comes to use it).
Note that the razor comes with a mower accessory lon mounts easily. As often this kind of "accessory" is less than would an independent small mower.
The carrying case is handy traveling.
Finally, the price therefore razor elite brand. To find a quality / affordable price, it should be used regularly and be partisan shaves "electric."
Refills of smart clean system are not data but also should change at a reasonable pace.
In conclusion: a very pleasant razor to use but very expensive.
