When I purchased the iGen2200 I expected it to a good quality unit. When I first used the unit when camping with friends, they had a high priced red generator. When I brought mine out they started to give me a bad time until I started the unit & they both stated it was quieter than the ones they had. After we ran for some time, they were once again amazed that mine ran much longer than the big bad red machine. I am extremely happy with this unit & intend on buying a second very soon.
