Not a parent yet, but I'd probably use something like this less as something to find out if there's a choking hazard, but in case there's something I don't think of that might be a problem. Fire hazard because it shipped with a faulty power regulator the overheats? Exploding batteries? Those are things that I wouldn't be able to tell at first glance that they'd necessarily be a problem.
How far does this rabbit hole go, though? Your kid may just as well be the first victim of a yet unknown fault. You can't protect them from everything and trying to do so will only cause you anxiety. Wouldn't you rather spend your mental energy on something more positive?
Agree. But I think that's the idea behind the concept. Don't want to spend time worrying about it, but if there is a known defect discovered later about something I bought, I would like to know about it.
Assuming it's as easy as lifting my phone and scanning a barcode after the occasional toy purchase. Then I can forget about it.
Agree you can't give up common sense, and you shouldn't obsess about it, but it's silly to not remove a toy if there is a known defect that causes deaths.
It also could give you a false sense of security in case it's something that's not published on this particular service.
Also, in most reasonable countries products that are known to cause deaths are removed from the market instead of continuing to be sold with the "buyer beware" assumption.
We don't need to do that and can't because the technology is incredibly complex and even if you understand that stuff your curtains could be the real fire hazard in your room.
All of this is covered by consumer protection laws very successfully - recalls.gov has just a handful a day across everything, Amazon alone sell over 200 million different products.
