I have a EU1000i that according to the output indicator light blinking at startup says it had over 500 hours on it. I've not done a thing to this little genset except put gas in it and change the oil with Amsoil synthetic a few times. It runs just as good as the day I brought it home.Less powerful. More expensive.
Honda has no equal in the generator market, that's just a fact. Others are inching into towards Honda's level but they all fall short somewhere. Mostly quietness since everybody and their dog are counterfeiting Honda engines. They also rule on power cleanliness, their inverters are the gold standard. I'll stick with Honda until I see one of the knock offs hit 2000 trouble free run hours, Hondas passing that mark are everywhere.
