The construction looks marginal. The engineering on the maintenance is nothing short of appalling. I have never seen worse access to critical maintenance areas. See attached picture of oil check/fill. The instructions for oil change literally say disconnect this hose, and tip it on its side to drain oil. Meaning you are likely not going to empty the oil pan. Since there is no oil filter, you better change the oil often, but it will certainly shorten the life. I am concerned about the vibration level. That could abate after break in. It started easily and ran quietly.

I bought the generator and was so pleased when I started it up. It was so much quieter than a typical open frame generator. After I started it, I took note of what appliances I could use without any problem. I'm using the 30 amp generator inlet box on my home. I could run everything I wanted. One burner on the electric stove, the microwave, refrigerator, oil furnace motor, (1/2 hp) well pump motor, coffee maker, and the lights. The only time the generator shut off was when we turned on the air fryer in addition to everything else. So I just restarted the generator (minus the air fryer) and we were running the whole house again. So obviously when you know you're close to the limit, you simply choose to wait a moment for one appliance to finish and then you can turn on the other one. I was also totally surprised when today I tested running the electric dryer without running anything else, except lights and a few low wattage items. The generator ran the dryer without a hitch. It was drawing 5400 watts and when the refrigerator started up, everything kept going. This wattage (9500 peak 7600 running) was the right choice for my home. I feel safe and secure knowing it will provide reliable power when we need it.

First Duromax. Setup straight forward from unboxing to startup. Took three tries to start at 14 degrees. Quality of fit, finish, control layout, owners manual all excellent. EXCEPT, access to oil fill. A Honda type oil fill extension is a near must.

I HAVE OWNED SEVERAL GENERATORS AND I CAN HONESTLY SAY THIS IS BY FAR THE BEST ONE I HAVE EVER OWNED IT IS SO QUIET AND EASY TO MOVE AROUND
