After re-ordering and returning sure it's a design issue. The bits themselves work well and look solid. However, the reason I gave three stars instead of four or five is because of the label. The label for each bit looks different than the photos. It measures bits in millimeters not inches and it doesn't show bits cut off so it's hard for me to find what I need quickly - I really have to go to a website and open pictures online and then find one in the same place in my box. Update 1: The seller contacted me and explained that the error on the label is due to a factory shipping error, but they have no solution to fix it other than offering a free return. I decided to bite the bullet and hope that the quality of the bit outweighs the inconveniences of the label. Well, then I discovered that a bit's collar screw had snapped off the first time I tried to remove it. I also checked the other bits and found that two of them were erased and one was almost erased. Now I have to return it. Apparently, this problem is much bigger than the label. The good news is that I've tried three of these and they all worked and stayed strong. Maybe I have another lemon.
