This is my first electric razor and I'm very happy. The first days, I tried to use it without lotion that it is economical and it was blah, it hurt shaved. Then I put the lotion and it's great, it's sweet. I never cut myself, it shaves almost. It is super fast to use and clean. Another important thing, I bought the model with the base and it does not serve much. It can automatically fill lotion razor in hand but it works very well too (see the 8420 model much cheaper.) With the 8460, it also has the portable charger and it's the one that I use . For the lotion is economical, I use the shaver for 3 months and I have not had to buy new lotion refill. Finally, another difference between 8420 and 8460: charge of speed to 8460 but it is not annoying everyday because autonomy is good on both.
