We have the part now since January 2010, and use it for a haircut (1 x of all 6 weeks). You can not complain. Cuts like the first day and still works great. The cable is long enough. We deliberately chose the model without battery and are happy about it. There is no battery, which could break down.
The settings for this device are very good. Slip the spacer is so far never. Cutting without the spacer is quite thorough and therefore very usable, if you even want to trim the long beard or would like to work towards a complete shave.
