I have only had this unit a short time, but it seems to be very well built. It started very easily on propane the first time I used it. It is quiet, has a good sound to the running engine and I really like the data center information readout. The threaded oil fill spout is a nice feature.
I just unpacked the unit and put the oil in and started it. It is quiet and meets my expectations. However, the remote control was not included in the package. And a deciding factor for my purchase.
I just purchased this item and am very happy with the ease of getting it ready to use. It started immediately with both remote and push button start. It is light and easy to move by carrying or pulling with the extended handle. After starting I let it run for awhile it is as quite as advertised. I bought this Westinghouse model after having go results with and older 2200 Westinghouse inverter generator that I have had for app 8 years with good luck.
I have only ran it for 5 hours so far and have no performance issues SO FAR. They only thing I will comment negative is the wheels and handles vibrate like crazy causing it to rattle a lot. Other than that it works fine!
30 hours in and couldn't be happier. I have run it on both propane and gas with great results. The remote start is super worth it. Battery was charged enough for the first start and easy to keep charged. I love the display features and a lit gas fuel gauge with is help to see the level at a glance. I run a 4 season camper trailer with a 30 amp panel, plenty of power to run my base camp. Good build quality and comes with proper paperwork like a parts list and schematic which I like to see and you don't get with most equipment anymore. 10 out of 10 and would recommend.
