The electric shaver needs to be changed every few years

At present, most razors sold on the market have a service life of 2-3 years. In order to maintain the initial state of the razor, it is recommended to replace the blade and knife net (knife film) every two years. If you want to shave cleanly with an electric razor, the most important factor is the tip. If the cutter head is not replaced for a long time, the effect will be affected. At present, razors on the market can be roughly divided into turbine type, wrong knife type and retina type.
