Plenty of power reserve.

This is a great unit with more than enough power for my home. The only thing it needs is a quieter muffler system.

This product is reliable

I purchased this generator for my home. And the electric start is a great help for my family. To run the generator if I'm not at home.

ease of starting

easy setup - started right off. only plan to use propane but don't like the fact that you can only run off 20# tanks

Whow it's a beast!

We just got our Gen set and could not afford a automatic standby unit. All I can say is this thing is a beast! Our house is all electric and we can run the whole house on this unit. For the price this unit is hard to beat!

Product is great except for the user manual

User manual could be a little better on how to operate the generator, I spent an hour trying to figure out why it was not putting out power. I finally figured out the problem. Other than that it looks to be a great generator!

Very happy with the performance of this generator

We ran this generator at 3/4 capacity for 4 days after a recent hurricane in our area while staying in our 36' Puma camper until our power was restored in our house and it did a great job!

Powers everything

Great value for the price. Have used it 4 times since purchased in 2012. I use it to energize the entire power panel so we can use water (well), fridge, stove, lights and AC. It's a bit noisy, so this is the one improvement I would suggest.

Good product and dependable

Although we have had this generator less than 2 months, we put 70 hours on it during one extended power outage in the area. It started up without a problem and ran flawlessly the whole time. So far, I have no complaints.
