We purchased this generator 2 weeks ago online when the lights went out for 36 hours. It was scheduled to arrive the next day (which was going to be great since we had no electricity). BUT it arrived 5 days later- by now we had light. Got it setup and initialized several days later. It is too early to tell about the performance, but It appears to be ok for what we need it for (only when electricity is off for 6-8 hours to keep a refrigerator, TV, and phone charged and running)
