This is my first purchase of a mitre saw and I find the unit well constructed and powerful for the projects I intend to carry out and keenly priced. The instructions are very helpful but you do need to sit down and read them carefully before using the saw for the first time. I selected this saw after reading several reviews and was disappointed to find that the table only rotates to 45 degrees not 50 degrees as shown in the reviews and there was no dust bag provided (The latter was not made clear in Screwfix catalogue main page for this item, apparently "Dust bag and Extract Facility" translates to an optional extra?
