Style: 19,300 Starting Watts
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

    • Won't even start
Style: 19,300 Starting Watts
I had a bad experience with Amazon after buying this. The first machine that was delivered had a massive dent in the fuel tank where it had clearly been dropped onto the ground from a height. I only found that out after unboxing (something that takes an hour because it's in a crate). I contacted Amazon who did arrange to have it replaced. When the new one arrived, it won't even start. There is something fundamentally wrong with it - the battery is good, it has correct fuel, etc. but the starter motor won't turn over. The local dealer don't know what is wrong with it and Generac are no help at all. ... show more

Style: 19,300 Starting Watts
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
