A webcam on Aliexpress is around 5 euros. Throw in a microcontroller that's like 2 euros on aliexpress, a 10 euro screen and you still have a 30-ish euro budget for the actual door that's probably plastic (acrylic and something like PE ?). So yeah, probably more expensive.
But that doesn't means that doesn't exists ! We can see that all the time in supermarket, but I guess their needs are different.
If there is anything I've learned in my country (with national health care) where it's common for doctors to ignore you and say it's nothing, is to be overly pushy and even rude. It could be nothing, but a lot of time instincts are correct, and it's a mild embarrassment if you are making a fuss over nothing, but could be a life or death situation. And you could argue that everyone behaving like this is making it worse, and that might be right. But I remember multiple national headlines in recent years where little kids died of pneumonia after being sent home because they ruled out infection, sometimes even after parents already brought the kid back for the second or third time to the hospital after their condition wasn't improving. I know I'm not making chances even if it means getting a second opinion or driving to a different town to a different hospital, sometimes it's better to take things into your own hands than be complacent and rely solely on the medical system doing the right thing.
My son almost died in the first 24 hours of life. I said, "There's something wrong. There's something wrong." multiple times and the nurses finally told me, "YOU NEED TO CHILL OUT." I did chill out....
Next morning the pediatrician did his rounds, checked on my son, and immediately started speaking Latin, to go over our heads while rushing around and getting equipment to clear his lungs of amniotic fluid.
Reminds me of what my first engineering boss told me -- "When the people on the line say there is a problem. There is a problem."
I learned english at school in France, and we're notoriously bad at teaching foreign languages. The approach is way to academic and mainly based on reading. That's why our accents are often atrocious. I was good at written tests, but what allowed me to actually get fluent (as in being able to think in english and convert my thoughts to speech in real time) was watching tv series in english with subtitles in english (no translation involved.)
This seems similar to the method used by Robert Greene (and Ryan Holiday who learned it from him, and many others.) I just started using it (as in: I bought notecards and a box to store them.)
I love FortNine, they always manage to be both funny and informative at the same time. And the way they do really long takes in their videos is really cool. Even the segment about the sponsors is well integrated into the video.
One of their latest videos (https://www.youtube.com/watch?v=GpVMsqSW6pk) contained a teaser about a documentary they're going to release in December: around the world in 17 days. Can't wait to see it.
I also have one (model A1263) bought on Amazon FR. Anker doesn't list it as recalled on their FR site. It lists others though https://www.anker.com/fr/rc2506
Maybe the faulty batteries were only used for some models/regions pairs ?
