I have only used it three times so far. What I can say is it is very quiet which is exactly what I was looking for as I primarily plan to use it for camping. The handle and wheels make it easy to move. I really like the electric starter and the lights and display are simple. It runs my camper A/C with plenty of power to spare. All in all its just what I was looking for.
The only problem was with the oil plug/level difficulty with reaching the plug threads. Making sure not to cross thread. The generator started up immediately. Very satisfied.
