This is the best electric shaver I have had so far. I have a very difficult beard in the neck. All other razors, especially those with rotating heads can not cut the hairs that grow through. This one yes. In addition, he shaved without having to force the skin. It is soft, lightweight, quiet. In terms of use, you should remove the power supply to shave. When you're used to hang a defeat that thread. Now I appreciate. The battery must be important because the engine does not weaken, even if I seek voluntarily for testing, long time. In addition, it is beautiful and very competitive prices. Apparently this is a German supplier shipped it to me. No problem except 2 or 3 additional days for delivery.
