I bought the Honda EU2000 and the Harbor Freight equivalent at the same time. I did the same break-in and service for both.
We kept experiencing long power outages in my neighborhood and I need to make sure my multiple freezers/fridges and kids entertainment centers wouldn’t be offline for those extended outages.
We always ran both generators with same fuel simultaneously with similar loads and run times.
I think it has been between 6 & 8 years.
The Honda is still great.
The Predator surges unless it is under load at a higher rpm.
Harbor freight made some slight improvements to the Honda machine when they “borrowed” their design, just not in the running department.
The Honda was almost double the price, but I kind of wished I had just bought 2 Hondas Or one larger Honda unit.
