I bought this to use as a backup generator and so far it has been excellent. I've had it for one month. I bought the LPG version so that I don’t have the hassle of petrol going bad in storage. I do not have any petrol powered equipment, so I would’ve been storing petrol just to power a backup generator. That said, I like that it can operate on petrol too because it’s nice to have options in an emergency situation. With one press of the wireless remote it starts instantly on both petrol and LPG. I tested the output with a 3.5kw load and it had no problems. It also started a 1hp induction motor easily (bench grinder). I appreciate the 4 year domestic warranty and 10 year spare parts availability guarantee! This generator will be rarely used in my application and I would be annoyed if it broke and I couldn’t repair it after only a few years. The only downside is that it is not cheap. Being quieter and dual fuel comes at a price. The generator is basically identical to the Westinghouse iGen4500DF that is sold overseas, so you can look that up and see lots of reviews. Shout out to Tim for the excellent service.
