This is the best generator you can buy when things go bad. I love this generator, it powered everything I need with out a problem.

The GP7500E exceeded my expectations on the performance as well as the noise level. Assembly was quick and easy.

Bought it two weeks before Sandy. We were without power for 2 weeks and it ran pretty much the entire time without a hitch. I highly recommend it.

This generator rubs my whole house! Including my well and electric water heater! I am just simply impressed!

We had an outlet burn out and the warranty would not replace. We also had to search several places to even take it too. Not an easy process

This generator powers my heat-pump,well,sump-pump and refrigerator no problem during a power outage.

DOES WHAT IT SAYS IT WILL DO SO FAR SO GOOD.If it continues to perform at this level i will be convinced

Just unloaded unit from carton. It started right up after adding oil & fuel. Will be using in any future power failures. Great product.

Very easy to use. Plenty of power to run our whole house in Florida especially with the Hurricanes!!

This is the first generator I own, so I am not very experienced. But I would think that it should run longer than 3 hrs on a tank fill up.
