This shaver has been tested on a 10-day beard and a 3-day beard. The grip of the razor is perfect and ergonomic. The battery holds a charge longer; it is not necessary to recharge the battery between two cuts. Charging is done quickly. The hairs fall into the receptacle provided for this purpose: no hair in the sink. The different cutting heights are very convenient both for the "3-day beard" as for longye beard; ditto for the mustache. The shaver is very easy to clean. short, product advisor to any modern man practicality
