Will recommend

[This review was collected as part of a promotion.] Easy to maintain, weight is moderate & easy to assemble. The output is great & seems durable. Will recommend 4 anyone looking to get a generator.

Great for an emergency

Although I only bought the generator a couple of months ago and have tested it once every month it seems to be fine . I haven't had an opportunity to use it yet for an emergency.

Peace of mind.

Starts easy, have not had to use it yet, I run it once a month just to warm it up.

Great product

Purchased the gp6500e in case of power outages from hurricane Irma. Works exactly how you would expect. Instructions could be better but common sense goes a long way. The single quart of oil brings the unit just past the low mark on level ground, good thing I had backup oil on hand. Battery came with enough charge to start it right out of the box. Has been running constantly with no hiccups. 9/10 Would buy again!

Oil Leak in 30 Hours

Purchased the unit the morning Sandy was to hit my area. The unit was very easy to set-up and operate. The only issue is that the unit has started to leak after only 30 hours of use. After speaking with a Generac rep from the 1-800 service number, I was told to operate the unit, check the oil every 4 hours and bring it in for service once power was restored. Not the reliability I was looking for, but overall it is still working. I hope the repair and warranty process runs smoother.

Great Product

So I heard Generac has a great reputation for making reliable generators and even though I bought a portable generator, working in the propane business, their are many where I live that are buying the permanent home stand by propane powered generators and they are reliable and even though my is portable but used for home standby too, its what I want. I know it will do the job and keep us comfortable and our keep our food fresh while the power is out. I have yet to get my electrical panel up to code and a transfer switch installed on my house, but when I do I will be able to enjoy the full luxuries of having power without power :) Noise level though its just like a lawn mower or any other gas powered engine, pretty noisy, but again, your inside and its outside and so i can handle the noise.
