Good maintenance can give a trimmer a long life, but sooner or later some components will need to be changed. In the case of rechargeable hair trimmers, for example, the battery may need to be replaced. For all products, however, sooner or later (we are talking about years) it will be the turn of the blades. In this regard, we must make a clarification, given that not all spare parts are found with the same ease. Spare parts for appliances of famous brands, and especially those of higher quality models, are much more easily available.
