About 90% of all my tools are Dewalt, so needless to say I'm a pretty big fan... But this laser is straight junk... Very hard to adjust and it doesn't stay true... Also you laser line will move as you are coming down to cut your material... To bad I can't at least use it as a coat hanger... Don't waste your money...
