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.

Starts up on first try. Quieter operation than most generators. Had it for over a year and it's never let us down. Great product.

[This review was collected as part of a promotion.] GP8000E COS W/Cord 49 St generator has ment all my expectations.

We have just purchased this generator and ran it once. a bit louder then expected but have confidence it will be good for our need.

Just assembled, Very easy. Simple instructions. Started immediately. Still have to connect to main panel.

Transports easily, powers most of house to include my heater, refrigerators, and most of lighting. Easy to use.

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.

Seems like a good generator. Only complaint is that it is very noisy. Was a little time consuming to put together

When your power goes out it tends to be a pain in the backside. This generator worked great for 15 hours with no problem at all. Very Happy !!

An excellent generator.it does everything it claims.l would recommend it to anyone looking to purchase a generator for home use.
