I would say its pretty good as far as mechanical goes,The hopper is made from the same kind of plastic as a halo but is pretty durable.I i like the rotor more mainly because I can break it down in the middle of the field and work on it. I have had only 1 problem out of it and that was the sensor bar in the feed neck but contacted them about and they replaced it for and even gave some extra screws for the body that I had lost.Customer service was awesome.
