This product js not so bad but its very complicated to use. To set the number of shaving we have to role the rounder. If we select 3 no then its not done at 3 no. 3 no means 3 mm shaving. But we cant get 3 mm shave. And it takes too much charging time. And usable time is 40 minuts only. Amd after shave we have to clean the teimmer. And its not easy. Many hairs stucks in blade.
