I ordered recently here on Amazon this battery percussion drill. I have flirted only with other mains-powered and battery devices from other manufacturers, but since I have previously ordered the cordless screwdriver Makita DF030DWE much choice on this device, since the battery wonderful match. I'm going to change little by little my equipment on this 10.8 V system, since it is sufficient for normal home use. The battery percussion drill I have already drilled holes in concrete first, (6 & 8 mm) without problems. Also in V2A stainless steel makes the machine does not move his tongue. You sound pierces the 9 mm I needed. And when the battery times limp made, the reserve was already loaded. All in all, I am fully satisfied with Makita devices because in our company use many partner companies also devices from Makita. And who work daily with the devices in continuous operation.
