I bought one of those $19.95 Chinese nose and ear trimmers that were advertised on TV for a long time, the one guaranteed not to cut or hurt. It took weeks to arrive and last about 6 months. Then I bought one of these.
This model is far more substantial with a good engine and nice cutting surface. Panasonic won’t guarantee you won’t have an unpleasant cut or two (especially in the nose) but it works well and is not bad in the pain department. Does a very nice job on ears, too.
I haven’t used this thing “wet” yet and really can’t imagine doing so. So far this has done the job and has been everything it was advertised to be.
