If the mower section is rather powerful and well done I rather regret the handling of the mower too massive for my taste ... Given the size it is not possible to take him on a journey that is finally my opinion.
For the razor part it does the job but it is in my view a breakdown, shaving sorely lacking in precision (on a hard beard).
L.autonomie is good about an hour but it is not possible to use in troubleshooting this one with a cord, pity ...
To: design, mower, autonomy.
Against: the lack of precision of the razor.
Conclusion: My opinion is mixed on this product which has the merit to combine both tools on the same product, the use table without being catastrophic is not living up to my expectations I have really enjoyed a better accuracy razor on a hard beard clipper for her being efficient and the product design rather successful.
