I recently purchased the SINOCMP 7Y-3914 Round Throttle Motor for my 320L engine, and while it gets the job done, it's certainly not without its faults. On the positive side, the double cable design provides added stability and the 6-month warranty is a nice touch. However, the motor speed can be inconsistent at times and I've experienced some occasional stalling. For the price point, I suppose it's a fair compromise between quality and affordability. Overall, it's a flawed but functional product that does the job adequately.
