Chuck runs rough

After I've studied the reviews and yet repeatedly criticized the non-circular chuck was I was unsure whether I should buy me the device.
But as to read more often is that it is so fine and the drill anyway at load centers I have ordered but the hammer.

And I promptly got a eiernde machine for defective suitcase Amazon sent me without hesitation a second set - same issue, eierndes chuck.

It may be that some people will not bother here and yes - you can drill holes with it, but sin clean precise hole pattern is a matter of luck. The drill runs in plaster but particularly clear.

With a quality tool in the price range I do not think that is acceptable, has Maikta without change chuck this problem does not seem (at least there is no evidence to the reviews).
Since I was quite disappointed with the quality but I have but decided against Makita and DeWalt bought at retail a similar price.
Drilling is therefore as simple and accurate as expected, an SDS-Quick chuck is attending.

Nevertheless, kudos to Amazon for the excellent customer service and uncomplicated.
