I had an old rotary razor brand and it is the day and night. Shaving is very very effective. I finally found the shaving quality that has the manual! The mower is also very effective and seems very robust. It's also great to be able to shave with foam. I still have less irritation. The adjustment of the speed is really a gadget in my opinion: we put speed 1 when it was time and 3 for a very quick shave. The clean system is a bit cumbersome, but its design is very modern. Small problem: the use of cartridges for cleaner rather than a bin is filled. The razor has a beautiful design and offers a pleasant grip.
