Is Diode Laser Technology outdated?

What’s wrong with Diode laser hair removal? You need to target each hair section so it will take you about two hours to complete leg hair removal. In addition the diode only has one wavelength so it is not suitable for light or dark skins. Many clinics have used it because there was no other choice. However technology is always improving and there is now a better alternative which is the soprano titanium with three wavelength making it suitable for all skin types. Also a bigger handpiece and and in motion technology means it works much much faster for later in the hall. Legs can take under half the amount of time when you compare it with a diode laser.
