Tool well thought out:
First good point: with the buttons marked in red and well designed, with pictograms, we understand without reading the instructions how to use each function.
The action buttons are highlighted in red value. Can not go wrong. We find:
The trigger with power adjustment knob above.
Just above a double button alternating the rotation between clockwise or counterclockwise, allowing in "screwdriver" to screw or unscrew.
Amidst a 3-position switch to alternate functions (see below).
And a final tightening knob to steer as you like handle.
An exception to the color red: the drills fastening system "SDS", which can be clipped easily compatible Drills (by screwing chuck is available if you have conventional drills).
Complete tool, so 3 different functions:
Screwdriver drill or screwdriver to position 1. "violent" anyway because it's heavy and it does not stop. Drill usable on all materials and tested on wood: easy to use, fast and efficient.
Impact drill in position 2. Easy to perforate concrete, little vibration or noise, even if it was not reinforced concrete.
Hammer mode only in position 3, which looks very good to see the run empty but I did not test "in conditions." Lets farting tiles or digging bled it seems. The chisel is obviously provided.
Finally, the last possibility may install a measuring abutment parallel to the drilling axis.
Some flaws:
Heavy as a drill, it may not be accurate in some works which require (drill or screw on wood, for example).
The carrying case does not fully hold the objects and these "travel" easily.
I do not see any other ... the price seems deserved.
In short, the very very good, very well finished and versatile tool.
