I bought this because I wanted a good small generator. Westinghouse claims this is a pure wave inverter generator. So I tested it. I placed this generator on my flat bed trailer, then I bought out oscilloscope. I was impressed with what my oscilloscope showed. This is a very good generator.
I purchased this generator the beginning of October and was vert pleased. It's light and easy to move. Starts up on the first pull every time. I would highly recommend this product.
