After many negative recessions Mannesmann tools I wanted them anyway even test yourself. the cheap price was very tempting. After about 2 years with the drills I'm very satisfied with the brand. The drills are all still sharp, though so a complete old building was renovated. Siebe after a drill was brought almost to glow in a granite stone, it has not warped and barely lost material. The same applies for wood borers, which are very precisely gearbeit and also for a roof, a terrace and show a climbing tower for children no signs of wear.
Short: sher recommended for DIY enthusiasts. I would buy again
