||These motors are 100% absolutely worth what they are listed for. These are half the price of the Systema Magnum and have extremely similar outputs. However, like every other motor, they arent without their flaws, however, the benefits definitely outweigh the problems.
STRONG! (hard to turn pinion by hand)
Great trigger response
Too strong (9.6v NEEDED, mine wouldnt pull the spring (M110) with an 8.4v)
Weak pinion gear (showing wear at 5k rounds)
LOUD, because of this precise tuning is a bit of a pain
Overall, a simple replacement pinion gear and you are 100% set.
