    When I received the generator, it had a broken air filter cover probably due to shipping. I called and they immediately sent a completly new air filter assembly. No questions asked and very quickly. Thanks!

  • Generator - Dude
    Verified Purchase

    Seemed like a great value. Ordered for my husbands birthday. When he started it up it seemed fine but very loud. We plugged in several different items nothing would work. The generator did not put out any electricity on any of the three plugs. Reset the buttons checked the gas still no go. Overstock was great about refunding and sending a call tag to return the item. Save yourself the hassle and don't go there with this item. We are ordering another brand to replace.

    I got this generator to send to my father-in-law on the east coast after the horrendous storm. For such a heavy item, there was no freight costs.

  • Saved my butt
    Verified Purchase

    Bought this geni after Hurricane Irene last year and did not use it. This year, it was put to the test during Hurricane Sandy. Ran my fridge, boiler and TV with no problem. A tank of gas lasted me 11-12 hours. A little on the noisy side compared to my neighbors Honda (paid $3000+ and hooked up to his electrical panel, mine did not.) Overall, a decent little workhorse that kept my house warm and bearable during a bad storm.

  • so far, so good
    Verified Purchase

    So far, it seems like a good generator, it took a few pulls to get it initially started, but after that, it started every time with the first pull. It was delivered with no damage to the box, but on further inspection, the bottom frame rail was bent just a little...probably happened at the factory, but I didn't want to deal with the hassle of echanging it, and the damage doesn't affect Anything. My freind commented on how quiet it was. That's it. Thanks

    After putting the gas and oil in the generator the cord was pulled and it started on the first pull. I was very empressed. I received delivery in about 3 or 4 days.

  • Great generator for the price
    Verified Purchase

    We only tested this once we received it to make sure it was working properly, which it was. Not hard to get set up. hopefully we won't have to use it too much. Only gave it 4 stars because I haven't really fully tested it out yet.
