We are committed to solving some problems caused by the traditional transmission method of fascia guns. How to achieve small size, large torque, as much as possible, low noise, low vibration, and not to make appearance for appearance, but from the inside to the outside. To consider the problem at a deeper level and solve the existing problems is the nuclear power of product innovation. The same shape and appearance change are the simplest way. Choosing a small motor to make a small volume is to sacrifice the original intention of this product research and development. As long as the shape is not the bottom line of the actual effect of the product, this should not be the direction of fascia gun product innovation.
