- I took it in addition to my DDF485, there is a special mode for screwing into a tree, a mode for unscrewing nuts with an automatic stop when they break, modes T1 and T2 for working with thin / thick sheet metal - roofing screws turn tolerably. There are also 4 screwing speed modes, there is a backlight - it goes out after 10 seconds (by the way, it can be turned off altogether if not needed). Of the pleasant things - a light-accumulative ring on the front that glows in the dark will help you easily find the tool.
