I just purchased and do not know of durability. Item is as described, getting the cover, for the oil fill location, was problematic without damaging the cover, otherwise a great product for the price it started, ran and powered an electrical item fine.
I have an old style 3500W generator... very loud, and heavy to move around. Needed something better, and this iGen2200 was perfect. After adding the oil, it was easy to start. Had it running to break it in with very little gas, it ran for almost an hour! Not very loud, I will be able to run it at night without the neighbors hearing it. Now it gets stored for its inevitable use.
I am new to the use of the generator. I will say I ran for 1 hour to break in and it was very quite. I then loaded with a half fridge and a couple strands of lights and the decibels hardly went up. I ran for 1 hour and it never quit. I purchased for camping and am anxious to try it out more.
I just received the unit and set it up (Great Instructions) I read all the reviews on this model and listened to the reviews on YouTube. When It first started I was shocked on how quiet it was. I then switched it to Eco and I thought it wasn't running it was so quiet...
The only issue I had was removing the side cover to add oil. It is very stiff and in fact, I broke one of the side tabs removing it. (I think I can glue it back on). I will put some white lithuim grease on the tab holes to make removal easier in the future.
