Long hair is very fast, and for the shorter stubble have to drive more than once a skin site.
This has also been mentioned in other reviews.
I've seen it myself but overall presented much more strenuous than it actually is!
In a dry shave with the device the result is sufficient for me. The hair is now and you can feel only slight remains when you drive through the skin.
When I'm in the bath in the water (ie under water) using the device, I achieve even results as with a wet shaving with a blade.
Due to the acquisition was with me that I had a problem after each wet shaving with a blade (disposable razors, reusable razors, razor, razor blade), because my hair is grown.
This problem I can hereby resolve, because the hair is just not quite as short cut.
