Product I received was defective

I ordered this to ensure good extrusion on my CR-10 as I had some janky stock parts that I wasn't very happy with. Installation was simple and easy but my prints were horrible. I suffered from inconsistent extrusion. I calibrated my steppers, replaced the tube, nozzle, tried different filaments at different temps. The problem was with the unit itself. I did notice that it was VERY difficult for me to feed filament through it. Perhaps there was something wrong in manufacturing that caused the filament to get stuck and hang. When I got fed up after tinkering all day I reinstalled the factory unit and now my printer is working fine. Super disappointed.
