I purchased two of the Champion 75531i for my DJ/Karaoke business. I got a great deal by ordering from Great Offer Stock. After they arrived I thought to myself that's why they were so cheap (minor damage). Well I followed the instructions and contacted Champion support instead of Great Offer Stock. They assured me that all of there products were shipped brand and that they were inspected prior to shipment. So not Overstocks fault. They are shipped from Champions warehouse somewhere in Ohio. They did say however that they had seen an increase in damage resulting from mishandling in shipping. Because of that they extend their warranty to customers that incur damage during shipping. They offered to set me up with the nearest repair shop or send the parts and I could install myself. I opted for the self install. This was on Monday, the parts arrived on Friday (along with two free generator covers). I had already ordered two from another distributor, so now I have four. I did all the correspondence through email using the support link on their website. Never had to place a call. They even offer to update my warranty with my sales receipt so I wouldn't have to mail in the warranty card. One of the parts that was broken was a left side handle. They sent another portion of the handle instead. Almost the same part number. (one number different). I emailed them back and the next Friday I received a complete handle. Left, right and back. I gased and oiled the generators and ran for 5 hours per the instructions. They run great. They are very quiet generators, though I can only compare to regular generators (or other devices that make noise) not Honda or Yamaha since I have never owned either of these. I plugged in an air compressor on eco mode and they didn't even blink. I have seen several tests where the sound levels are measured from the exhaust end of the generator and its about 56-58 db. I noticed that from either side, left or right, that the level is even lower. I later ordered two of the champion 25 foot generator power cables for these but they did not fit. The cables have a 3 prong L5-30P plug and the generator has a TT-30R outlet. Can probably be used with an adapter. I emailed Great Offer Stock and they sent me the prepaid return postage label so I can return them. No hassle. Overall I think these excellent for the price. In the end you will have to decide if they will fit your needs. For me they were just what I needed price wise and performance wise. I see the price has dropped since I purchased, so now would be a good time to buy.
