This nerve is working well, pretty comfortable to hold, draw with a very good rate (about 4 bullets / sec). However, it is better with other accessories like guns extensions, viewfinders, hockey sticks and other chargers. Even if the scope is less than 20 meters, we can without much difficulty increase the voltage and therefore the speed of the balls. It must be said that this nerve is noisy and therefore very discreet. Buy them if we can customize it with other previously purchased nerve.
