Have not had to use it yet, but it is a nicely put together machine. It had all the labels to make sure you added the oil. Adding the wheels was easy. I added non-ethanol fuel sta-bil. It's ready to go.
Had this one day and can see the utility! Instructions very easy to follow. Can run my AC for a 2600 square foot home and a mini split AC for a 400 square foot room over a garage simultaneously. Getting used to the running sound volume. Transfer switch and 50 amp cable is the way to go.
