Let's start with the positive, the box is made of very durable ABS plastic and actually would be a very good solution for almost all related screw-work in the private sector.
The content consists of a bit holder and the bits of course. Although the bit holder in my box is running smoothly, but the sleeve is dependent, ie you can not hold on to "Anfädeln" a screw this example. When virtually identical metabotropic set (usually only costs a few more EUR) has been always works flawlessly. When Bosch set I have now already tried the 4th and all have the same problem. As other reviewers from other problems (off-balance, etc.) reported, seems to me to be probably a kind of serial errors - depending on when / where the batch is produced, it has this or that mistake with "regularity".
The bits themselves are rather high subclass, the alloy is only slightly harder than a butter-and-cheese mixture. And so see the bits then also, when used with a proper screwdriver. TX20 and T25 were both about 30 screws "round" (5 or 6 mm in diameter, 60 ... 80 long - so nothing "special").
It may well be that IXO power screwdriver thus can make friends, but once the screwdriver provides a decent torque, it seems to me rather to be a short pleasure all both because the alloy used and because of the fit of the bits. My tests resulted in any case consistently at very modest results.
Robert Bosch reported to have said, I have always acted according to the principle, I would rather lose money than trust. The integrity of my promises, the belief in the value of my products and in my word, stood me higher than a transitory profit. - Unfortunately line is little left of the spirit of the company founder in the green BOSCH.
