My Bosch GSR 10,8-2-LI Professional drill is used in a carpentry shop. For use gravity interior design find the 10.8V always sufficient. However, there are colleagues who insist on their 14.4 V or more cordless screwdriver, must but then lug around the heavy thing with himself. For very heavy work (eg. As window frame screws), I use the hammer drill with SDS bit holder. The charger charges the battery in the nearly 0.5 hrs., That is very fast, especially since you also still the second battery has (lt. Bosch is the battery in half the time, so 15 minutes, loaded with 75% of maximum load ). The drill has a battery level indicator with 3 LEDs. The Bosch GSR 10.8 is optically the Makita DF330DWE very similar. The Bosch expands in length about 2 cm shorter and the handle of Matkita is slightly thicker. The switch forward / reverse can be operated with your thumb or forefinger, so no need to enclose a screw to solve. The switch has a lock, that is, he can not be with the machine running accidentally press (Makita dto.) The differences between the machines are low, I like the Bosch something better.
