+ High-quality, one can safely say "professional" version of drills and chisels
+ Stable aluminum case
+ Very well balanced range (eg: replace Bad-flow is thus a delight)
+ With the SDS drills with 21 and 26 cm in length can also be a lot of breakthroughs in the home (eg, for a good, old cable management ;-) cope
+ Price / performance very good
for a sporadic yourselfer might not necessarily, but otherwise highly recommended
