Simple but well constructed. Quality materials. After reading other reviews before I used it I put a restriction in the pick up tube. It was mentioned it uses a lot of media. After I was pleased with the consumption. I used Black Diamond coal slag and it worked well. One tip for you...stand up wind it blows water too! Make sure your media is higher than your washer wand so water doesn't feed back into your media container. The price is right and I am happy pappy.
