Many customer reviews stated that you can not even chucking the drill supplied with this drill which I initially appeared quite skuril.
After I read that you just have to screw the drill to find a second chuck I still bought the drill. When he arrived, I still had the problem that I could not clamp all drills, although I unscrewed the drill and the chuck applied. Just minutes before I wanted to send the drill again, I noticed by chance that I had done wrong: you can both screw the drill front to turn around the chuck, also the drill to take the rear screwing a new two other sizes are out.
The drill itself served its purpose and would get me 4 stars because the price is my opinion, reasonable.
Nevertheless, there is a star trigger because on the packaging and the drill is not the slightest hint is hidden.
