I have the Makita Cordless Hammer bought after I have worn several cheap screwdriver from discounters in recent years without much use. For "greater responsibilities" they were not suitable (too little power) and if something was a little thing to do, the battery was either instructive or already broken due to low usage (Ni-Cd battery). The Makita makes a good impression because it is more versatile and because the lithium-ion batteries can be expected to last longer. The first practical tests (multiple holes in concrete walls and filigree work with 2mm drill in steel) it has well passed. Very good, I also think that the speed of zero can be increased very emotional - very important for some work. In summary, a versatile and powerful machine whose "perseverance" can be increased by a larger battery.
