No issues with the unit. All parts arrived without issue. The included controller works properly as well. I did as one of the other customers did and adapted it to an 1 1/4 galvanized pipe with a floor flange. Just had to drill out the holes. I think people expect that the generator is going to turn as freely as it does without any electrical load, when its under load. The more electrical load on the generator the more force is required to turn the generator.
