Whoever already has a battery, can access calm.

Processing is totally okay. Handling simple.
Some 6 and 8mm holes drilled into a concrete pavement with reinforcement. I used 4-flute drill of Würth.
Work could be opened without effort, what is very comfortable especially on a circuit. I was just so tired of working with impact drills and their Zahnkranzgeschei. For the more common household of the hammer drill is ideal.
I used 4Ah battery. After about 30 6 mm holes in the charge status still showed 4/4.

For comparison, I had borrowed a 36-volt battery brands Rotary Hammer with 2.6 joules. Furthermore, I have a very old, cable-based Hilti.
When using the same drills the appliances were a little faster, but also more difficult. Just have one or two classes higher.
My concerns, the Ryobi had enough clout for ordinary concrete, have proved to be false. The 3 seconds per hole, the Ryobi are longer needed so bad. Precisely because you can work with one hand without force and with the small machine.

One battery machine is 20 years old I do not expect anyway. For that reason I do not see it to pay a 600 euros for brand cell phones and batteries. Anyone looking for a hammer drill for life, there are units with plug of example should. Hilti look.

I can not give a definite buy recommendation.
