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.

Better than expected.
75 hrs in and this thing has been a life saver. I bought it as a just in case for a trip we were taking our camper on to run the A/C and charge the batteries because we didnt know if there would be a power hook-up, since our campers A/C unit only uses ~500 watts the GM1200i was the perfect size. The morning that the generator was set to arrive a plane took out some power lines leaving us without power and to make things better it was the hottest day of the year. The generator showed up about 1PM and I spent the next couple hours doing a break in of it. 1hr zero load, oil change, 1 hr 25-50% load, oil change, and then 1 hour 50-75% load and then an oil change. That was perfect timing as it was getting to the hottest part of the day when we could plug in the camper and use the camper AC and watch some TV to cool down and this generator did perfect. We did have it at about 900w for about 30 min while the camper batteries recharged and we ran the AC and the TV but once the batteries charged we went back down to about 550w and it ran all night until ~4 am when the power was restored. We did also end up needing it on our trip and we ran it at night and for an hour or so and during the day when we had to plug in laptops and such to do a little work and this generator handled it like a champ. It is very quite as we are unable to hear it in the camper even when it is just out side of the door, we even had someone stop by and comment one of the times we were running it during the day and about how quite it was even under 50-60% load. This generator is also really good on gas for the entire week we were out we only used right about 4gal of gas ( 4 of the 8 nights we just used to charge the batteries to run the inverter since it cooled off and we didnt need the AC at night). When we got there we had about 14hrs on it and we left with 74 hrs so that is about 15hrs on a gallon of gas at 25-60% load. The only con I have about this generator is that the plastic access panel for the air filter is very loose and will fall off while running, I put tape over the clips to hold them it just it was be nice if the clips were spread just a little bigger so they would catch better. TDLR: Very quite, does it job very well and it very fuel efficient. I do recommend doing some kind of break in process on it as the first 4 oil changes did have a good amount of glitter in the oil but by the 4th oil change it looked normal. I personally did oil changes every hour for the first 3 hours and then about every 25 hours after that. If you need a small generator to run lighter loads I don't think you can go wrong with this one.

No support from Amazon or Manufacturer
My Genmax 1200i was delivered yesterday. The packaging was in good condition. The generator was securely packed. Everything was in the box that was listed. I added oil and gas. It started I believe on the 3rd pull. Ran great with the eco on and off. Plugged in some test devices. It shut off after about an hr. Checked the oil- good. Checked the gas- good. Made sure the gas was turned on, I'm old, I forget lol. Started right up. Would run 15 min - 2 hrs and shut off. Contacted Amazon for product support. They referred me to the manufacturer after some stupid unrelated questions from their customer service. Contacted the manufacturer. Waiting........... I will update when or if anyone gets back to me. Right now I suggest you not buy a generator from Amazon. They don't care. Update: Still no response from manufacturer. I have not been able to talk to a live person, only leave messages. Update: It's been 4 days I didn't hear from the manufacturer. Called Amazon again 1st person transferred me, 2nd hung up after telling me nothing they could do. I called back, transferred. I was given a different number for the manufacturer. I finally got a real person. They are going to send me a new CO sensor. Nothing as of today. I guess I'm on my own. Received nothing. 3/26/2024 I suggest no one buy a generator from Amazon. They don't allow returns on any generator. You have a 50/50 chance of getting a generator that works. I can't afford them odds. I'm still able to charge my batteries, sometimes for 10 minutes sometimes I get an hr+. That's unacceptable. Will not run! This has been a piece of sh*t since day 1.
