I bought it mainly because it had four and a half stars. Too bad I didn't read some of the reviews. I used this set for the first time and bent the drill bit! I think I pushed too much although I didn't go crazy because it was a good direct operation. I've never bent a drill in my life. I broke the small ones, burned a few big ones, but never bent them. I can't believe how soft they are, they are like soft steel wire. I wonder how long these things will last. I can't imagine them staying sharp because they are so soft. And I wonder if they're even going to dig hard enough into anything. I recommend saving your money and getting the best set. Even at the low price I don't see them as a bargain. And don't think that the number of stars reflects the quality.
