    • Sturdy built generator.
Style: 8000-Watt + Electric Start + COsense
It is a well built generator at a good price. It is easy to start and runs well. It is easy to move around on large wheels.

    • Excellent
Style: 15500-Watt + Cosense
Used daily for our business It's loud but easy to use. We use non-ethenol fuel in it & change the oil before the recommended & have had no issues. Have almost 500hrs on it. Quality is good, runs well. I wish it were cheaper, but compared to others it's in the money. We had a duramax prior & it didn't run well & ended up frying our equipment. This one is OK for electronics. Would recommend ... show more

    • Powers out so what"
Style: 3600-Watt + COsense
First of all we bought this generator when the demand was high. Most of the stores were sold out. But Amazon saved the day. Great price and I didn't have to go out and get that heavy thing home. Now I don't panic when the power goes out. Great product and free delivery with prime. Thank you Amazon.

    • The directions produced good results.

After a few electrical connections, and installation of wheels, the generator started up! Another worker is needed for a safe installation.

    • Parts Missing
Style: 15500-Watt + Cosense
I like the build quality. I'm currently breaking in the generator, runs great. Made in USA definitely a plus. Value for the money spent is good compared to overseas models. The issue is that the axle for the wheel kit is missing from the wheel kit box. You'd expect better quality checking before shipping. Currently have been on hold w/ Generac support 25 min. I got a very nice girl to help me with this issue, so we'll see how good the support is. I'm getting the axle @ N/C under warranty. The drag is the 7-10 business days for shipping because Generac doesn't expedite shipping. UPDATE: Generac did UPS me an axle kinda quick, so kudos to them for that. Generator is running fine so far for 10hrs on brake in, only glitch was having to reset spark plug gap to proper .030 as it started to sputter a little. Spark plugs are gapped wrong from factory @ .018. I'm a auto tech so not a big deal. So far I would recommend this unit. It is well built, not bad on fuel so far & I'm picky. Also I like the fact it has AVR instead of capacitor regulation. Better for electronics. ... show more
