After the failure of a primitive old hammer drill I've been looking for a replacement. After starting with the cheapest impact drill from Bosch green it started :-) Although I am really more than equipped very well, I "love" me in the removable battery system 10.8V. With a little research you realized that the Bosch Blue System has the best price performance ratio. Then of course you ordered a system with 2 batteries and the L-Boxx. - From then it will get expensive. The system is so awesome that I now more L-Boxx-en have and other devices such as the multi-cutter and the saber. Although I have the equipment as 230V variant. But for many applications is usually the battery system already full enough. The comparable version you can watch in Bosch-green everywhere - but then you should compare eg the torque.
