Rated 4 out of 5 by from Quality out of the box, one pull start, only used 30 minutes as first start up trial. Unit packaging was quality, instructions and assembly of wheels to frame and feet as well as handle was simple. Manual was easy to read, follow for warnings and pre-start up instructions. Unit started on first pull, expected maybe two just to get gas through system. Ran for about half hour to give it a bit of a break-in. Plugged in a few lights and other items to give each circuit a trial. No problems, ran and powered as expected. Not sure what other review stated about eco sense issue, I had no issue as I used the product outside and away from building approx. 4 feet. No issues on my initial trial run and expect this product to do the same after the next big storm hits our area.

Rated 5 out of 5 by from Amazing craftsmanship This will be my second generac generator I have purchased and both of them started right out of the box with the first soft pull. I let them run for a bit and then load tested them with no issues. Everything on this generator is solid stable and reliable . Hats off to the design team, and assembly workers at the manufacturing plant.

Rated 1 out of 5 by from Awful, do not buy with the COSense We have extended a tailpipe 5 feet up from generator exhaust, it still senses the Co2 and shuts off, no help from Generac other than taking it to a mechanic and I know the problem is the sensor. This has only been started to test, sadly, we were past the 90 days to get a full refund, we bought in case of a storm related power outage. Very disappointed. Now I will unhook the CoSense and this will void the warranty. Hard to go out and restart every 10 minutes if being used post storm. It was advertised as built in US with 2 year warranty, tag states made in China.

Rated 5 out of 5 by from This generator did a great job. We were without power for 4 days. My sister is on electric oxygen and has a portable oxygen that needed to be charged. We traveled over an hour to find this generator. We also needed to have power for our refrigerator to keep our $600 in groceries from being ruined. I would like to know if it could be back fed to my house but for the moment it ran for 15 hours on one tank of fuel. Our 4 days on generator sure eased our stress for not having power.

Rated 4 out of 5 by from Reliable with a large tank We lost power at home and had to buy one of these in an emergency for our fridge and freezer. It seems to work well. The only issue is that it says that it should not be left in the rain, but yet it has a CO sensor. We had to figure out a good ventilation situation in the garage to make it work, but it would be great if they could be left outside in rain storms. Oh well... Next design?

Rated 5 out of 5 by from Easy Assembly, up and running Quickly Just brought this Generator, easy to assemble and got it connected up as a back to my home in less than three hours. Tested it out and runs everything we need to have powered up during a power loss. Good value for the money

Rated 4 out of 5 by from Return buyer I have owned 4 Generac portable generators, this last one has a CO sensor, and I don't like it. If the wind blows even a small amount of exhaust towards the sensor it shuts off while outside! I will be calling tech support to see what to do about this problem. Otherwise I love this generator.
