Its like a good insurance policy!

Very pleased with this product ,starts very easy and quiet. I have done a lot of research, and borrowed generators, I'm so glad I went with a Generac.

Great Portable Home Backup

Order after Hurricane Irma did in our 12 year old generator. Great price for the features and power output. Took about 10 minutes to assemble, put gas in and it started right up. Would recommend. Power cord is a nice included additional item.

Product performs as advertised

We run an industrial meter with our unit on various jobs. The unit starts up right away with very effort. Very reliable and sustains the power when we need it. Would highly recommend this product on almost any application.

Works well on the jobsite

I have mine installed in a custom trailer and use it to power all my electronics, AC and hydraulic system. It's been extremely reliable and easy to maintain.

Nice Generator

Generator works as advertised. Starts very easy with electric starter. Very little assemble work. Handles just about A load with very little loss of RPM. Would buy this all over again if I needed another.

Great features at a value price.

Very pleased, my generator came with a lot of nice features as standard that many other brands don't even offer, or charge extra for as upgrades. Highly recommend Generac products, great features, and value priced.

Excellent performer

The GP6500E is exactly as advertised. It is a well functioning unit and easy to use. I couldn't ask for a better generator for the price. Im especially pleased with the electric start which is a big benefit for us older folks.

Trouble out of the box. No support

Unit surged badly right out of the box. Would not provide reliable power when it was need desperately needed. Could t get support when it happened and now faced with decision on what to do with a useless heap of metal.
