Plenty of power for any job.
The light is perfectly placed and allows good illumination.
battery life is very good (18v 2.00Ah)
Removes any and all screws and bolts I've come across with lots of noise!
There is none I have come across but I could of done with a small case. I'm currently using the plastic bag It came in, even a small fabric zip bag would of been good!

Brushless and apparently will last longer than on with brushes
It didn’t have a case with it, although I bought the ‘bare’ model as I already have the drill and 2 batteries
