works like a Champ!!!
Would Recommendwe use this to run our mobile embroidery and printing business out of our trailer set up at events and shows. we pull a great deal with embroidery machines, heat presses, vinyl cutters printers lights and fans.

Started on first pull
Would RecommendRead instructions, followed them to the letter, halfway through the first pull it fired up and is quiet compared to my general. Tried several appliances and it provides enough power for my needs.
