Overall quality and design is UNDERSTATED, hands down one of the best units I have ever owned.
Outstanding generator. We use this as a light weigh portable unit, fully filled with oil and gas its 30 lbs. Generator starts easily, runs quiet and sips gas. Carries its full rated load even handles surge without any issue (1600 watts). Highly suggest using Mobil 1 0w40, ran it for 2 hours and flushed the oil, ran it for 3 hours and flushed the oil. Definitely needs the break-in flushes. After the second flush oil stayed clean and handles full load without struggling. Economy mode drops the noise level by probably half, ideal for battery charging or where you're not needing its full output. I was extremely impressed at how they built in access to all the service areas on the generator. Absolutely designed with easy servicing in mind! Oil changes, spark plug and other areas all have quick access panels making routing serving not only easy, but require no additional tools. It comes with a filler spout that hides inside the generator for oil fills and changes. Another nice feature is the gas tank vent shut-off. This eliminates the worries about spills, but also closes off the tank for keeping gas fresh. For storage, the service access panels allow easy access to the carburetor drain, Also, there is a fuel shut-off valve to run the carb dry for storage to avoid gummed up carbs and no starts when you need it most. Overall its a solid 12 out of a10 in terms of quality, design, function and far exceeded my expectations. We purchased two of these, one is used for our airplane (preheaters) and for our Son and his detaling business powering buffers and lighting.

Great Portable Power for the Price *UPDATED*
*UPDATED 6 Months Later* I am so pleased with this little generator. Since my original review of using this generator for running compressor and power tools, I finally had the opportunity to run it for the purpose I bought it for; running a small air conditioner at my no-power hunting camp. The generator performed exactly as expected, and was able to run the small 5,000 BTU air conditioner as well as some lights and providing me an AC outlet in my hunt camp camper for my phone charger for 6+ hours in 90 degree temperatures on the one gallon of gas. The generator is light enough for me to transport wherever I need it, so I have used it to run power tools on other "in the woods" projects to run my saw and nailer, electric landscaping tools and other plug-in equipment at my hunting stands. My latest experiment involved trying to run the electric systems on my 17" popup camper on this generator. With the 13,500 BTU rooftop air conditioner, as well as the Absorption-type fridge, and the main lights (2x LED banks) the generator was able to run everything. Once the AC ran through its start up cycle (large, temporary draw) and went to steady draw of about 1300 watts to run, I was able to run everything in eco mode, and did not overload the generator. I am incredibly pleased with the output of this generator and the small fuel consumption, small footprint, and relatively quiet operation. I would definitely purchase this again if I had need to replace this unit, or if I had increased power consumption. *ORIGINAL REVIEW* I purchased this generator on a Lightning Deal. It was a little bigger than what I wanted. I needed a small generator to run a 5000 BTU window AC on a camper I use at hunt camp. I was looking at the smaller Genmax generator (1200) but saw this one at basically the same price. This last weekend I had the opportunity to put it through its paces helping a friend build a cabin on a remote property he has. This generator was able to run a compressor (to run a framing nailer) as well as a chop saw for cutting dimensional lumber for framing, and a circular saw for cutting zip board. We even had an extra outlet we used to charge power tool batteries. The generator would struggle just a little bit if the air compressor and the chop saw ran at the same time, but it would catch up quickly and push on through. We ran the generator continuously for 6 hours on the single tank of gas. While its primary purpose will be to run the AC unit, I am now confident that I will be able to also run lights and perhaps even some appliances at the hunt camp trailer. The generator was quiet enough to be able to have a conversation standing next to it without really raising your voice. In fact, it was quieter than either the air compressor or the chop saw when they were running. All in all, I am very happy with its performance over the weekend, and I'm sure it will be more than adequate for what it was originally purchased for.

Not bad
I'm quite happy with this thing especially for its price I've used it twice heavily. The first use was just Running a 850 W Golf cart battery charger For about 6hrs It was surprisingly fuel-efficient And ran perfectly. The second job Was running a small electric snow blower 1800 W 15 amps Exactly the running power this thing is supposed to put out. While it did run the snow blower It was struggling I triggered the overload shut off twice. Granted I was pushing the limits of the snow blower as well doing a massive job in deep heavy snow. The over load warning light blinked a lot but it pushed hard for 2 straight hours. I will also be useing this for Electric weed whackers, chainsaws, and large flood lights. I don't think it will have a problem with any of these however my only real concern now is how long will it last. "Update did not last" My only complaints Is if you pull the string to far forward the friction will actually melt the plastic on the side slightly not a big issue. "Update oil Sensor brick the whole thing" Update 1 1/2 months later. The generator no longer starts it continually tells me low oil regardless of the amount of oil. I am now removing stars. There is no scenario where I should be having to tear this thing apart to fix something as simple as an oil sensor Inside of 40 days This has caused big problems with my home. The directions do not even tell me exactly where the sensor is And the entire thing is encased in 2 layers of plastic so I can't get to anything without tearing apart everything. Nor are there any tutorials and simply unplugging the sensor Did not work either. Also the Provided schematic Has the wrong color codes on the wires. I now have a $300 brick. No customer support Can't find parts. Just s*** out of luck.....Never again
