How many hair trimmer I've already tried ... I can not count. Many are cheaper but considered just about the moment. Since the batteries last a maximum of 2 years making really tired until it or they do not cut more cleanly after a short time. Replace battery? Wrong! .. ... Not so with this unit! As is also shown how to change the battery .. a Lithium - Ion battery mind you. What surprised me even unpack how well the device in his hand anfühlt.Es fits snugly in the hand and has just the right Gewicht.Sieht already really great and makes a high impression. The adjustment with the rotary wheel is stably integrated and also the removal of the cutting head does not cause problems. Cuts outstanding and is still enormously soft case. The cutting attachments are made of plastic, but they are quite flexible, so that my needs have no fear, because the same from breaking something .... I know from other devices quite different. The long cable of the charger makes working with connecting cables without any problems. After cutting you can leave the unit in a stand and not flying around in a drawer .., class The cleaning of the device is also very easy. It is clear that the device is not the cheapest, but if I all the other devices so look at me that I've had before and have only held until shortly after the warranty, this is already something very very different. Then this hair trimmer also has a lithium-ion battery does not matter .. as limp after 1000 recharges! As I said a super great device ...
