    It works great and has never let me down. I’ve used it for a variety of projects, from home repairs to metal work for my company and it just keeps on going. The only downside is that it’s noisy, but then again, what do you expect from an industrial machine?

    Worked flawlessly. Simple to set up immediately after receiving it, there was a power outage, so I’m glad we have had it.

    I have three freezers, one refrigerator, and many more appliances, so this is more than enough to power my entire house. Obviously, the fact that ALL of my home’s lighting are currently LEDs helps. But I was able to simultaneously run a water heater, a house water pump, four box fans with celling paddle fans, and three window units.

    Based on our current use we would recommended this generator to everyone. It is very solid generator and meets our needs. We purchased this generator because we live in Florida and hurricanes hit us often. For a low cost high powered generator that runs gas, you won’t find a better option. Very happy with our purchase!

    I am very happy with this portable generator. I was looking for a generator of this size and it’s perfect for my needs. It arrived in good condition and runs well. I am able to power the whole house on it and so far, I have not had any problems with it at all. The shipping was a little slow but that’s due to freight line delays.

    I opted to buy the 18kw Big Dog when Hurricane Ian caused a power outage due to several friends recommending this brand. I intend to have this generator running throughout my entire house when the next power outage occurs.
