No, I don't think your mad, but maybe on the cheap side ;-} Sounds like these drives are not well made. The technical name for the size is [https://www.ifixit.com/Tools/MacBook-Air-5-Point-Pentalobe-Screwdriver/IF145-090-3|P5 Pentalobe] we really don't get into the dimensions of the bit. You may want to use a pick to make sure the screw head is not filled in with junk. Also, Apple uses thread-seal, I often need to use a soldering iron to head up the screw (don't get any solder on it) to soften the thread-seal a bit to get the screw loose. The last action is a drill if the head is damaged or sheered off. Just be careful with the metal shavings!
