I bought the trimmer to cut with 3 mm thickness my beard a week and am very disappointed with the device. You have the trimmer about 10 times over the same spot lead to get a reasonably Satisfactory result. Also you have to constantly solve the attachment to clean the accumulated Barthaar jam. Horrible and very annoying. About 4 years ago I have even a no name product from Aldi for 15, -gekauft and was very happy until he has given up the ghost. Well, since it is believed Panasonic would produce quality but this is not so. They should stick to television sets. The get the more out. Conclusion: Not recommended. A waste of money.
