Rated 5 out of 5 by from Solid generator for the money I have owned this generator for about 3 years. As long as I use fuel treatment or completely run the gas tank empty before storage, the generator starts up on first or second pull. This is due to ethanol in the fuel. I use it on our farm and as a back up for power outages. It will run both A/C units in my camper with ease. My only gripe is the area around the fuel gauge is recessed. I left my generator outside during a heavy period of rain and it collected water which seeped into the tank, requiring me to drain and clean the tank. If the area was flush this could have been avoided.(or next time don't leave my generator outside like that.) I also experienced the problem of my fuel gauge becoming discolored and unreadable. I just open the tank and look inside for fuel level now

Rated 1 out of 5 by from Powerdial start never worked Set up and used same day as purchased. RS8000E over $1000 cost. Powerdial rapid start never worked, so forced to pull start each time. Customer service response was it is likely bad or low battery. Charged battery & also bought brand new replacement battery, but powerdial rapid start still does not work and makes no sound at all when turned to start and pressed in. Ridiculous for brand new generator electric start not to work right out of the box.

Rated 5 out of 5 by from Excellent for the price Got the generator for the hurricane season in Florida but, no hurricanes affected me so it stayed in box for a year. We got prepared for Dorian to arrive and got the generator full of gas and oil and it started on the first pull and I had it running for a few hours with no problem. Ran the refrigerator, fans and a portable A/C unit and it handle it well enough.

Rated 5 out of 5 by from Power to spare Purchased this unit after hurricane Irma hit. Was borrowing the neighbors gen for the first 5 days we were without power, but they came home and we needed something to run the house. We powered multiple fans, tv entertainment center with 5.1 surround, refrigerator, 6000btu window shaker a/c and multiple portable electronics around the clock and this generator didn't flinch. Started on the second pull. I have no doubts it can handle a bigger work load the next time we need it.

Rated 1 out of 5 by from Not easy to use Pulling the chord is too hard and won’t start. I read the manual and it is a disaster. 2.5 hours and it won’t start. I push the button for rapid start and nothing happens. Pulling the chord is impossible. Not recommending at this time.

Rated 5 out of 5 by from Great experience Well here we go again. WE bought this 4 years ago for Hurricane Michael and did not need it. 2 years ago we had Hurricane Irma and it ran like a champ for 2 days. Now we have Hurricane Dorian coming and while we are in Jacksonville Florida we may not need it, I took it out of the garage, pulled it 3 time and cranked like a pro. It runs everything we need. Thanks.
