I never really got the point of them since they were usually for things that stored really well and get used up at a relatively constant rate so it's usually not a surprise when you run out, so like why would I need to rush and blindly push the button to buy more detergent/toothpaste of a certain brand without knowing the price when I'd just eventually buy it in my normal shopping run/order.
They were fun. I bought a few back when they were $1. It’s more fun to press the red bull button than to say “computer, order more Red Bull.” I didn’t really use them that much because amazon’s prices got a lot worse so I ordered my Red Bull and batteries from other places. I hope I can repurpose them for other iot signals.
I bought one for that - it's authenticated on my wifi but doesn't know what to order on Amazon. Pushing the button will make it visible on the network but do nothing else. So I wrote some scripts to run when it associates on the network, works pretty well.
