Damn, only 23 incidents caused an investigation?

There are 31 "reported" in total. Its porbably more, but there  are plenty of people who don't report hardware failure and simply throw the things in the trash or take them back to the store for an exchange/refund rather than go through with the claims hassle.

My bad....31. What's that? like a 0.05% failure rate?

What would be your criteria for investigation then? How many units have to fail in the exact same way in completely different places before you would launch an investigation?
