Maybe I'm missing something, but I'm not even sure how blister packs help protect against accidental overdose beyond the protection you'd get from just counting the pills in the bottle. In either case, you could accidentally skip a day and double dose later on based on the number of pills remaining, especially if you aren't sure what day you started taking the medication. I can definitely see the benefit of a product that doesn't rely on user reporting to track doses.
