I bought the roller blocks as a supplement to my miter saw. When cutting baseboards and the like I'm so far always crawled around on the floor and have any squared timber or the like placed underneath to bring the strips at the level of the rest of the saw. Now I can work comfortably while standing. The blocks can be continuously to the desired height and allow a huge increase working comfort to a comparatively ridiculous price. For the handyman an absolute recommendation !!!
