Very happy with my product thank you

A Real Work Horse

I put this engine on my duck boat and it performs so much better than the predator 420 engine I had on the boat. This 500cc runs smoother and has a lot more horse power and torque and runs at a higher RMP than the predator engine. I'll definitely be using these DuroMax 500cc engines for other projects!!

Exactly what I wanted, well-made, a perfect fit.

the best

this is one of the best bad ass generator s i have ever seen thank you

I'll have a lot better luck reviewing it after I've received it

Duromax generator

Very pleased with Alex from Krato Power. He took the time to call me to let me know the generator was out of stock but expected some a few days later . I got my generator in a timely manner and it was in great shape . Thanks Krato

Excited so I pre-ordered

Although these are not in stock yet, this will be the best fit for my home. I have a 2200 sq foot house and was worried I would not have enough to power the A/C during a power outage along with the well pump and sump pump. I called in to make sure I had the right fit and Alex was so helpful and kind. He went out of his way to make sure everything was the right fit. This generator will hookup to my homes natural gas line, which is also what I wanted.
