Despite sparse hair main engine power was at least higher noise levels to its limits (shave a week) - then you have to start a little more frequently.
With very thick hair with a higher length, it could cause problems here.
The volume is quite high.
Battery life is fine, has served with me for 2 shaves (head and beard). By the beard of the essay, however, is quite bulky - grade the jawbone and under the nose because one has problems.
For the price completely ok. If you want more, must pay more.
