As you will learn in the video, it was missing 2 bolts to hold the gear assembly to the cross bar.I will also go out and buy lock washers because during use the bolts that hold the gear assembly loosened completely and threw the nut into a hive frame.Also after this first use, I had one of the knobs on the acrylic cover snap and almost cut me as it is cheap metal.Go buy real cabinet knobs to replace the chinsey, fragile, sharp metal when shattered knobs.Otherwise it performed as needed.
