I like the ease of starting and how quiet it is. The handle makes it easy to move since it is pretty heavy. It runs a travel trailer with ease, without the need to refill every 8 hrs.
After alot of research we bought the westinghouse iGen 4500. The box was damaged but the contents were still well protected with no damage. Followed the directions for fluid filing and battery connection and it stated right up. Did the 5 hour break in and then tried it on or camper. Quietly runs our 15000. Btu ac and all electronics. Very happy with this purchase.
