I put 5 stars because the product is really good, but the fact that I didn’t see the marriage right away is my fault. After repair under warranty, the unit is like new. PS will be more careful when receiving the goods and carefully test the first two weeks of operation. Its pros: Bosch quality! Convenient and powerful unit! Quite light in the hand lies like a glove. Two batteries included. Its cons: It came with a factory defect, there was a shift in the axis of the chuck, so the clamped tool described an ellipse (barely noticeable). The verification period has expired, so I had to contact the service. But the service fixed everything under warranty.
