There are now reviews that complain about low power (6-screw in wood is apparently not). Clearly, from the small cordless screwdriver with 3.6V you can not expect any miracle power. My house I have built years ago with real netzversorgtem screwdriver - there are also 6-screws and even more no problem. Even today there are plenty of bigger and stronger models with large NiMH battery with 9.6V to 14.4V, which have appropriate power and create such screws loose. The small cordless screwdriver I need for occasional work on, for example, PC cases, furniture hinges, hard to reach places in the furniture, etc. I have therefore also an entire living room Shelf split (with one battery charge) as well as 4-seater and 5-he screwed Spax screws in the wood panels. It went! It is important for me that the screwdriver, the charge does not lose by the Li-Ion battery during storage. Even after several months in the drawer he still has power, I can report from a device with a NiMH battery not. Not to be underestimated is the handiness and the enclosed bag with space for some bits (to be worn on belt), the battery charge indicator, the LED lamp and the possibility to use the screwdriver either as a straight screwdriver or offset screwdriver that the application in tight spaces very user-friendly and makes possible in the first. Conclusion: certainly not suitable for the home furnishings, as auxiliary tool for the craftsmen at smaller works highly recommended.
