I also owned a Kipor 2000W inverter-based generator and was very happy with it for the price paid ($400 delivered, via eBay). However, it did take more than one pull to get started, I chalk that up to always shutting off the fuel supply and letting it run dry before storing. There is no primer bulb so I had to do quite a bit of pulling to get the fuel to flow and start running. But once it was going it ran just fine.

I used mine for about 4 hours/day while camping several times, probably a total of 80 hours. I also used it at home to provide power to essentials during electrical outages. This past fall I ran it 24x7 for 5 days, only shutting it off to add fuel, and once to change the oil after 4 days.

I'd change the oil and clean/gap the spark plug after extensive use and at least once a year, always added fuel stabilizer and ran the carb dry before storage. Aside from being cranky at start-up, never a problem.

I sold it a month ago with my camper and have been looking for a replacement. Even though I have a larger generator for power outages, this kind is so quiet I get no complaints if I leave it running overnight, and is powerful enough to keep the refrigerator and furnace going in the winter, or fridge and some fans in the summer.
