Test description:
Location:ipi Institute für Produkt-Markt-Forschung in Stuttgart
Time frame: March 2, 2016 to April 8, 2016
Test subjects:
100 clean-shaven men between the ages of 18 and 65, who shave at least three to four times a week and who are willing to pay €150 for a shaver.All participants use a shaver with an linear oscillating system at home.The test was carried out on a three-day beard and a 24-hour beard.
Test design:
The test shave was conducted at the test institute under the supervision of a test manager.By shaving in split-face mode, the Series 9 was used for one half of the face and the other half with the Panasonic Lamdash 5 upgrade (ES-CLV9A).The following day, the shavers were reversed and each was used on the other half of the face.The shaving time per half of the face was measured by the test manager.After shaving, the test subjects rated the following shave attributes for both halves of the face with the aid of an electronic questionnaire: thoroughness, speed (efficiency), removal of residual hair, and gentleness on skin before and after shaving.
Results:
In shaving attributes such as speed (efficiency), thoroughness and adaptation to problem areas as well as the measured shaving time, Braun Series 9 was rated significantly

95% confidence level) better on three-day beards than the Panasonic Lamdash 5 upgrade.Both shavers were rated equally for the attributes thoroughness and speed (efficiency) on a 24-hour beard.Gentleness on skin as well as the removal of residual hair in problem areas for both beard lengths were rated equally for both shavers.
