I got this cage from the 2s entry kit that OOD sells and the quality seemed really good. However, when I was putting the flywheels on, the plastic cracked all the way through on the screw side and made it unusable. I'm sure it's a great product and I'm sure other people have had great experiences with this cage, but just be careful when putting on the flywheels and not to overtighten the motor screws as I did.
