After recently helping my family member install his new WGen9500DF generator (with a separate purchased amps/watts display), I purchased this WGen5300s to replace our 6 year old unit. In the past week, I have setup as per the instructions and tested it under no load conditions during the break-in period. It has started, operated & checked out just just as the reviews stated. Although our old gen has been very reliable during the Gulf Coast electrical power outages, we believe this unit will be as reliable, use less fuel & operate more quietly. We also like that the new unit is backed by a 3 year vrs 1 year warranty. The only room for improvement that I would suggest for the WGen gens, would be to add an amperage &/or wattage indication to the VFT display panel. We look forward to years of reliable service for our WGen3500s.
