Positives:
powerful
good workmanship
no annoying beep when the speed adjustment
pleasant (but loud) engine noise
Space saving because Endfall a charger
Additional tools can be rebuy
good and stable luggage (pleasantly small but with room for accessories)
Chuck is so far ok
Price is acceptable
Negatives:
heavy or top heavy
a little loud (considerably louder than a cordless screwdriver but less than an old drill)
Speed adjustment could be sensitive
Speed adjustment could start at a lower speed
Only a transition (on the trunk is 0-700 on the drill bit is 0-800)
no engine brake
AC power cord should be slightly longer
Conclusion:
As a substitute for a cordless drill, the machine is ok. Finally no more expensive batteries rebuy.
Really miss I do only the second gear at a higher speed.
That it hardly gives alternative (Netzbohrschrauber) and due to the good quality of workmanship I forgive 4 stars. Nevertheless, there are still potential for improvement. Other essays I do not use so far. Let's see how long does the engine.
