It was easy to put on the wheels, add oil (the full bottle), and move into location. Battery connection was a very easy plug in, and it was charged to power the unit upon arrival.
Overall very happy with purchase, have not had to use yet but set up was pretty easy although it was a little glitchy with the remote start set up and we had to call for tech support. We followed the directions on the manual but it needed to charge for a while.
Luckly I haven't had a power outage yet but I have hooked it up twice to test it out and it worked perfectly both times. I killed power to the house powered up the Generator put the house on it,ran A/C,Hot water heater and ran water until the pump came on and it handled it fine. Really pleased.
