I need the cordless screwdriver occasionally to, deburring metal parts that have been drilled on larger machines with a sinker. For this purpose I was looking for an inexpensive, lightweight cordless screwdriver with gears. As a "universal machine" for "professional home improvement" might be a little stronger the thing, but I did not want it. If you ever want to screw a long wood screws into the battens or something, should you buy something stronger. The chuck has a decent quality and good concentricity. The entire drive unit sits a bit loose in the housing. This can be seen only when you hold the food firmly and pressed around the enclosure. At work this small deficiency does not interfere. However, the very narrow grip is a matter of taste. This is not much more than a broomstick. At first it feels handy, but can be uncomfortable with prolonged use. So far, the machine has been running properly and the second battery is usually charged during the work before the first empty.
