Be careful not to confuse PSB 18 LI-2 (with percution - this model) and PSR 18-LI2 (without percution). The screwdriver-unscrewing / Drill is extremely powerful and very fine by adjusting the mandrel. The batteries are perfect for two because we can finally work continuously, 3 LEDs on each battery shows you the level of charge. When you start to screw or drill, an LED lights to illuminate your work (it is a real strong point). The charge is quick (1H: Lithium-Ion) and no battery memory problem. The automatic clamping chuck is very convenient: no question of injury by squeezing harder a bit. Change direction of rotation is very simple. The weight is rational in relation to the size of the machine. The pair of 18V is incomparable for crafts which refers to screw screws in a lot of particle board for instance. I almost forgot: there are two => speeds for an even finer work. I have not tested the percussion, but it is certain that it will eventually use it to drill a couple of holes quickly without having to get out the big drill. I may be biased because I'm a big fan of Bosch for over 15 years (I have more than that because of the reliability and service).
