The Modify TORUS Reinforced gearbox is an excellent investment for any V2 GB User. The strength of this gearbox will amaze you. I have abused this gearbox on extreme ROF (55BPS) and high FPS (520). I have opened this gearbox multiple times and have not stripped a single screw or the gearbox. The screws are of very durable quality and it comes with a tool to remove them (great for any tech). I see no signs of this Gearbox cracking anytime soon. So why 4 1/2 stars? The main issue is that larger inner dimensions. I have have had difficulty lining up the bevel gear to the motor. It made the shimming process longer and more frustrating. But once set, the gearbox will not fail from the stresses i have run it through.
