    Purchased this unit at the Grisham OR store in September of 2014. Brought it home tested it (all OK), used during a power failure this winter worked fine. I got it out to go camping and it would not idle. Called Champion and was told it was a fuel problem, not covered by warranty. I would have to pay for all repairs, TWICE. I own many gas operated items and have never had a problem even my 50 year old Evenrude outboard still fires right up. All I can say is, don't buy this unit without an extended warranty from someone you trust because you will probably need it.
    Cons: Bad Instructions

    After a disastrous bout with a off brand, it wasn't a hard choice to come back to Champion. My main power plant is the 4000/3500 that has started and ran flawless at every temp from -40 to 95 degrees, using 10w30 synthetics, Altitudes from 5000 to 9800 feet above sea level. Needed a smaller unit to back our camping and emergencies. Again, chose Champion to take care of our needs. An as expected, this little unit 2000 watt inverter easy to set up 10w30, treated fuel, started first pull, love the eco mode, whisper quiet for our needs, full throttle is friendly. Powered up our camper with no signs of peaking wattage (lights, fridge, microwave batteries water pump). Don't expect it to run your 13-15000 btu cooler, it won't, so don't bother trying. Don't like how you need to change the oil, but I will get over it! Bottom line is, Champion just works. Very reliable and cost efficient. Camping World staff in the Idaho Falls area was great, I will be back to their store again! Happy RVing to all.
    Pros: Quiet, Easy to Use, Light Weight, Reliable

    Excellent quality generator

    I expected it to be cheaper quality but was pleasantly surprised. However there was a slight issue with the unit right out of the box...after I took the side cover off to add the oil to the engine I noticed that the inverter unit was crooked, it had fallen out of its mounts. Looked like it might have gotten jarred in shipping which could have caused the rubber feet on the inverter to pop out of the mounting slots. Anyway, it was an easy fix to loosen up the enclosure screws and place the inverter back into its place, screw it down and button everything back up. The controls and switches appear to be good quality and the unit overall seems to be well-engineered. The inside of the enclosure is well-insulated to provide maximum noise control. I also liked that included was an oil filler funnel, a spark plug wrench, a USB plug and a pair of battery charging cables included with the generator. After adding the oil (not included) it started right up and ran smoothly. Hooked it up to a couple of lights for a load and let it run for 30 minutes, all was well. I bought this for backup power for my home heating system and it should do nicely running my gas boiler and a couple of circulation pumps. Even in non-eco mode the unit is very quiet, in eco mode almost unnoticeable from 25 feet away. I would recommend this to others who, like me, feel like layout out a kilobuck for the Big Red brand of generator is way too much! I gave this unit 5 stars. The long term reliability is unknown at this time, so I'll revisit and update when I've used it for awhile.
    Pros: Quiet, Light Weight, Features, Price
    Cons: Lower quality
