I'm in the midst of a project that requires 98 wooden beads with a 4 mm drilled hole. Found what I needed on Amazon so ordered 2 packages of 100 beds each expecting some of them to be unusable or defective. They came promptly but the holes for most were 3 to 3.5 mm and the first package I opened contained only 93 beads. The 2nd package had 105 beads. Rather than go through the aggravation and the delay of sending them back and having to look further for what I needed, I spent 2 hours re-drilling the holes to increase their diameter so I can use them. What has irritated you but you ended up doing because it was necessary or expedient?
