The unit is heavy duty and heavy in general. Take note that these things can be dangerous. It would seem to be self-explanatory, simple process, and for the most part it is, but it is worth the time to watch a couple videos. I did get a bind in the cable one time and had to pull the tangle out of the cutouts in front of the drum. The edge guards of these openings lasted minutes at that point; wish those were adhered better. All said, I am very happy with the purchase.
