I own such a razor for over a year now.The razor is very small - a little bigger than a matchbox. Doesn't take up much space on trips and travels. Quiet operation thanks to a special engine shock absorber.
The shaver is charged via the Type-C port. One charge lasts for a month with 2 minutes daily use. IPX7 water resistant - can be washed under running water, which is very convenient.
Rotary razor - two knives rotate in the form"Sun". Such razors are suitable for long and growing stubble in all directions, for example, it often happens in the neck area. The shaving head is spring-loaded, floating to certain angles.
