Once I was very well read about the product, I can the various reports and statements simply confirm. Battery life is limited (perhaps as 3-4 full beard shaves) but the battery is recharged in no time. Two different essays: Once an attachment that lets you get the short beard length (in 2mm increments up to 10mm) and an attachment for a not very short hair length (in 2mm increments from 10mm). Both can be reliably cut. The essays sit rock solid and ensure an even cut. If one removes the top, you have a long side for a precise shave. On the other side one has a separate trimmer with a small side, with which you can specify the shave even better.
