Fantastic machine. It solves your hands. It may not have the power that another sds plus or sds max tool with the same or even less money will give you, but it cannot be compared to anything in terms of portability. You can do your job anywhere without worrying about power. Its power is more than enough for drilling and grinding in concrete, and its batteries last for a very long time. Now, if someone wants to never run out, they can buy another set of batteries. Among the many advantages of the tool, its weight is certainly one of them. Although a little bulky, I personally find its weight low and it doesn't tire me at all. Of course, we are not talking about work on a ladder and with stretched arms. There, you definitely go for a much smaller sds type drill.
