The difference is that the cost of the instrument is different.
Technically, the cost of instrument laser will be higher than that of instrument RF and microcurrent to a certain extent. Because of higher safety requirements, it will be more difficult to control all technologies. Therefore, the general price of laser-type instruments is not less than 2,, but the RF ranges from several hundred to several thousand. Because the cost of instruments can't be reduced, and at the same time, it is necessary to ensure the corresponding profit space, and the price is also different.
