Women carried the carpal canals

Hello,
I tinker a lot, and the hands and arms tired;
This drill is perfect for me, light, powerful, 2 batteries.
(Beware there is another model with NiCd batteries, less)
I would not go can not be drilled concrete.
The box allows you to have everything on hand when I tinker in the garden.

If I have the choice, I always order on Amazon.com 100% confident.
