Charging the battery took about three to four hours. For me no problem, even if there are other devices can quickly. It's doing a second battery.
The screwdriver itself makes a good impression, the housing is fixed and nothing wobbles. Screwing and drilling works for me without problems.
Even though I do not use it longer, the Li-ion batteries do not have juice.
The AutoSelect function is self-explanatory and I find them good.
Overall, I am satisfied, price and performance vote for me. Other manufacturers require substantially more for 14.4 volts and 2 Li-ion batteries.
