Query: Complete Junk

My first attempt using this was to open an external HDD enclosure. I inserted the Philips head into the screw, began to turn, and watched in horror as the entire end fractured off. Not just the little screwdriver tip, but part of the square shaft just above the tip actually fractured off. This wasn't a difficult (read: really tight) screw to remove--it's something that you can remove a micro screwdriver that you would use to fix glasses.Again, this was the first time I used it and it was already broken! I suppose I could have kept it, but without one of the screwdriver tips I just threw the whole thing out.
