I have the trimmer for half a year in operation and use this about every 3 days. The device is handy, light, not overly loud and easy to clean. In my unit, and my use of the battery lasts often 4 weeks. I've had a lot of expensive equipment, which had to be disposed of mostly after 2 years - partly due to a faulty battery or defect on the shaving head (both of which would have been unprofitable for the exchange). In short -a good device and for this price unbeatable.
