This trimmer works very well but it's difficult to change the tools. They must be lined up just so and it takes some work to get them to seat correctly so everything's together as it should be. Once put together it's a very good product. Good variety of cutting length tools as well as an excellent nose hair cutter tool.
One problem I found when trimming my beard... the soft grip handle collects hair clippings and they are very difficult to get off the handle. I have to use a towel to clean the handle. I'd rinse it but the directions tell you not to get the trimmer wet so I can't.
