They want the total quantity for each lot number. I have a partial box of one lot that is recalled, so I enter 8. If I had another full box of same Lot number, I would enter 18.
I have 2 boxes of another lot number, so entered 20, but it said that lot was not recalled.
I thought it is dumb they have you enter name, email, birth date, just to check your lots. Then force you to prove you are not a robot. REALLY !!!.
I entered bogus info for those fields to quickly get my lots checked.
As for the 1 in 2 million, I found where it stated 1 in 2 million where a medical event occurred. So, probably more failures, but people realized it wasn’t working right, and replaced sets, or attributed it to something else without thinking set was at fault.
So having used 2 recalled sets, I can say that I did have some unexpected fluctuations in the past week, but did not even consider the set was potential problem.
I have 2 recalled lots, 5170774, 5143656.
And 2 not recalled, 5185640, 5185643.
