The positives:
Absolutely stunning, yet each hole has come to 8mm in the wall. Not quite as fast as with our 400W- hammer, but quickly and without cruelty. Hammer performance as promised. 10mm I have not tried it yet, but I trust him.
Good is also the (limited) use as drills (higher speed, no hammer operation) and the full-fledged use as screwdriver (lower speed, no hammer operation).
The device is easy to grip and not too heavy. However, much more difficult than the driller PSR from the same family.
The recording also almost 6-Kant bit holder, etc. In order to quickly switch between drilling and fastening. Provided you have the appropriate SDS-Quick drills for wood and metal, you can work quickly with only one device, the change of the tool is almost as fast as the handle to the second device. A not to be underestimated advantage when eg working on ladders. The second tool fits in your pocket, if necessary. Also between the teeth or to the magnetic bracelet.
That, however, you need to know and the product description is silent:
In hammer mode, the battery life is very poor, 6 to 10 holes then the battery needs to be changed.
When you come into this embarrassment (eg at a wood paneling on the wall), this at least requires a 2nd battery, better 2 and in addition the quick charger, otherwise one is slowed down quite quickly and needs to take a break, if you can not switch to a power supply.
Due to the SDS-Quick Recording any existing SDS drills unfortunately can be used ..
Small drill diameter (4mm smaller) eg for wood and metal can be used only with additional keyless chuck. Those with SDS-Quick Recording does not exist to my knowledge. This makes the device considerably larger and shifted the focus of very unfavorable, which drilling with thin drills quickly leads to tool breakage.
The speed for metal drilling particularly smaller diameter is actually too low, there's a right (Battery) drill advantage.
Summary: A great device that does what it should: drilling in hard concrete extinguisher. Unfortunately, only a short time, then the battery is empty. For occasional capes pictures, lamps, cabinets absolutely useful and belongs in every household with concrete walls, as with us. Larger projects are feasible and only with additional investments or a network device. A good (Battery) drill replaced this unit is definitely not what you would have brought the fifth star.
For me, therefore there 4 stars, ie the expectations and promises in advertising were fully met. 5 star there would be if beyond something right class would (eg drilling), 3 star and there was less defects which I do not see here.
