Majority of my work is new masonary washdowns. A quality extension wand is a must for the detail that I must acheive doing this kind of work. With one rebuild, my extend-a-wand lasted me 8 years. They are no longer available, so that's why I need another. I would even buy a used one. I don't have any complaints with the one I've had all these years. You just have to know how to use it properly. Scott
