I have a 2016 Massimo 500 Made by Hisun and it is a beast. I have worked the crap out of it hauling dirt, rocks, firewood, brush, etc. I have pulled up smnall trees with a snatch block on the winch. In short, I have done everything I can think of to break this thing and it still goes. I can't relate to the naysayers except that it doesn't run quite as smoth as a Honda or shift as smooth as some of the others but that's the $4000.00 trade off.
