Function:
All drill / bits I've ever used function properly.
Processing:
The workmanship is good. The drills are reasonably sharp and it can work well with it. Bits snap clean and interlock with the screw head. The material is reasonably stable and the bits are thus not so easily broken.
Price-Performance:
Good p / l ratio because it is for that price then only once well equipped for smaller applications home. Larger Set's are considering the amount of drills and bits considered better but I have rarely other parts needed or the often used to go then but eventually broken.
Criticisms:
no.
Conclusion:
I would buy the product again and am satisfied with the quality. For my application, the drill / bits are suitable therefore I forgive 5 Stars.
