I couldn't figure out for the life of me how to get the harness setup... But using it to clean a Duplex, just man-handling it, I am thoroughly surprised. This is only the second Vevor product I've purchased, and the other was an auger which got the job done. This really does feel well built, though. When it's fully extended, there's a small amount of sway, sure... But I think that's to be expected. It does not seem to be anything that puts excessive stress on the lance/wand. I'm really pleased with it.
