Not too much sound. So far, I have used it for 30 seconds, so can't say much but they insist that I leave a review, so here it is.

Super quiet and packed full of features for the money. Love it so far. Break in and first maintenance was easy too.

Bought a couple of months ago and used today for the first time. It ran great, was very quiet and worked as expected. Love the remote start also!

Haven't had a chance to use it yet, but the install and setup was very easy with excellent instructions.

Easy to set up! Generator started very easily. Much quieter than expected. I love the remote control feature. This was a great purchase.

I just purchased the dual fuel generator and I am so happy just to hook it up with propane and use it. I love that the system is enclosed, no assembly was required and it was easy to set up and start with electronic ignition. The engine is quiet for a generator and will keep us out of the dark and warm.

I bought this for my travel trailer and love the features of remote start, quiet operation, long run times, collapsible handle, large wheels, and the multi purpose display. Its size is perfect for my F150 and fits under my bed cover so people cant see it. It is a little on the heavy side for one person to lift in and out of the truck but can be done. Easily powers the trailers A/C unit with power to spare for other items. The dual fuel will come in handy if I run out of gas while camping. The only reason I give it 4 stars instead of 5 is that if you leave the battery switch on overnight with the generator off, it will drain the battery defeating the use of the remote start in the morning. So at the end of the day, you have to turn that switch off, which will not allow the unit to start until you turn the switch back on.

Got the generator today and ran it for a few hours. There were no issues running but I wished they would have provided only enough oil to fill it. There was just a bit more than needed and it flowed out a bit. Not a big deal just actually the only thing I found. Otherwise it seems a very well made generator with well though out packaging. I used the propane setup and it was perfect.

Decided to grab a medium size generator to survive a few days without power if needed. it arrived in great shape. unboxed, added the oil and connected to the propane tank that was connected to my gas grill. pushed the start button and it fired right up! I tested it with various loads ( ie hair dryer, heater, coffee maker). handled it all really well and its not obnoxiously loud.

While I haven't even had a chance to start my new generator, I did experience its operation at Elk camp this year. A friend owns one and it ran super quiet and flawlessly all week on a 20 gal. propane tank. However, my new one arrived today and I read the operator's manual front and back. I followed the directions on filling it with oil. Unfortunately, there was too much oil in the container that was provided, and as I removed the funnel, oil started pouring into the engine compartment and onto the garage floor. I would say that nearly a full cup of oil came out. What a mess to clean up. Now if some of you are thinking that my garage floor is not level, that's not the case. I also got some nasty cuts on both hands due to the sharp edges inside the various compartments - so I advise wearing thin gloves when possible.
