After 10 years of using the SE5, I looked to buy the equivalent current model, but in the end I ended up with this one because of its longer battery life. The difference is like night and day compared to what I had for so many years. It does the job completely painlessly and in 1/3 of the time! I started with the armpits and I was very satisfied with the result. In the end, in just a few minutes, you can do the whole body without multiple passes in the same area. Also, the cleaning is much easier, and it makes less noise. It was worth 100%
