High-power motor
The Models G 10SR2, G 12SR2 and G 13SR2 are equipped with high-power motors and are more powerful
than the current Models G 10SR, G 12SR and G 13SR although they are compact and lightweight. We could
say that the ratio of the motor's maximum output to the product's weight defines its performance. Compared
with a typical competitor's model in terms of this indicator, the Models G 10SR2, G 12SR2 and G 13SR2 prove
to have the highest performance.
