love the easy start

Haven't actually used it yet as we haven't lost power. BUT I had a friend put it together for me and he showed me how to start it up and it is so easy for me - I'm a girl and sometimes these mechanical things are tricky for me. I'm not dumb by any means - but I'm very busy with full time work and raising kids and was caring for my elderly Dad (who helped me buy the generator ... by the way). So, sometimes I don't have time to figure out stuff ... anyway it's a nice product - only complaint is it doesn't say how much of the oil you package with the machine should be mixed with the gas - we assumed all of it but ... and I am concerned about the gas sitting in it. I had to fuel it up to be sure it worked after I purchased it, but since I haven't used it and may not for a while ??? I'll read the book to see! Thanks and please don't share my personal info. Thank you again.

Built Like a Tank—Ready for Anything

[This review was collected as part of a promotion.] The Generac GP9500E is a beast. Tons of power—easily runs the essentials plus extras without breaking a sweat. The tri-fuel setup is a game changer. Whether it’s gas, propane, or natural gas, it fires up quick and runs smooth. Noise-wise, it’s not whisper-quiet, but for the power you’re getting, it’s surprisingly reasonable. You’ll hear it, but it’s not going to rattle your teeth. Maintenance is straightforward—keep up with oil changes and check the air filter now and then, and it’ll treat you right. COsense is a solid safety feature, and the build quality feels like it could survive a small war. Or a zombie apocalypse—because let’s be honest, if the world ends, you’ll still have power while the neighbors are burning furniture.

Just what I was looking for

Recently bought a gererac gp6500e after my old one of 20 years quit on me. Wanted an electric start option, which this one has and I also wanted more watts. Went from 5000 to this 6500. Although I have only had it a couple of months, I did get it oiled up, gassed up, and got it running. Ran great, less noisy than my old one and can run most everything in the house. Time will tell but so far it seems to be what the doctor ordered.

Excellent Generator

This is a great product for the price.The generator starts easily and runs fairly quiet.The fuel tank is huge and i can get about 8 hours out of a tank.I gave it 4 stars for only one reason and that is because of the wheels.This generator is very heavy and they should have sealed bearings on the wheels because when you have to move it on grass it is hard to push or pull.

Excellent Choice

I bought this equipment to be able to supply energy to my residence due to the passage of Hurricane Maria through Puerto Rico. Its fuel consumption was high but it did not fail me at any time. Easy to perform maintenance. I recommend it to anyone with closed eyes.

Another Quality Generator GP8000E

This GP8000E has most of the features I was looking for in a replacement/upgrade Generator. Electric Start is a must for me, Hour meter for Maintenance intervals is a great feature, low oil shut down, and charger for the battery. This unit came with Plastic "No Flat" tires that I find are harder to maneuver the unit with over the driveway lip, gravel etc. these obstacles are mini stopping blocks for these tires compared to pneumatic tires. One noteworthy item I was surprised with is no oil filter as my older Generac has a spin on oil filter but that's not a deal breaker for me. With GENERAC's quality and reputation I expect to get another 10 plus years out of this unit as I have on my old Generac that will be passed on to a family member home for back-up there. Overall i'm very pleased so far with my upgraded unit. I would recommend this unit for any homeowner as back-up power.

Solid construction and easy set up.

I spent the extra couple of bucks to get the electric start model for my wife. I'm in law enforcement and if I'm ever stuck at work during an emergency, I want it to be easy for her to set up and get things going. Right out of the box, set up was easy. Followed the directions and fired it up with the electric start. I let it run for a bit and it didn't seem any louder than any other generator that I've been around. Very happy with it.

POOR WARRANTY AND PRODUCT

I bought this generator just under a year ago. We were expecting power outages up to several weeks. Glad that we weren't effected. The reason for my 2 stars is the Generator is supposed to have a great warranty. Buyer beware, after putting the generator together and trying to start it the generator failed to start. I called to have someone to come out to check the generator and was told that I had to bring it to a place. So a generator that weights over 100lbs with a full 7 gal tank of fuel they expected me to transport over 25 miles to have it serviced. I would NEVER buy another product from this company.

Fantastic product that goes above and beyond my original needs!

[This review was collected as part of a promotion.] For camping trips and times when my neighborhood experience power outages, this generator is able to power my table saw, chop saw, circular saw, and keep my Fridge running without any struggles. My family took it camping this past weekend and we were all pleasantly surprised at how quiet it was! It is much lighter than my previous generator as well. With two small children and a small wife I needed a device I could easily lift into the back of my truck myself and this one fit that ask and all of my needs and beyond!

Worked perfectly

I was contacted by a neighbor that our area had lost power, and bought a GP6500 on my way home. I followed the operator manual, it started right away and I was able to save the food in our freezer and fridge. In my mind it has paid for itself. This is just the right size to cover critical needs during summer and winter storms.
