I'd be super-interested in buying this hardware. A few thoughts: 1) One of our (indoor, house) cats is always keen to escape, and as such currently wears a breakaway collar with an Airtag attached via a 3D-printed holder, which seemed the best available solution. He copes with that without a problem, so if this isn't too much bigger then I'm sure it would also be fine, and I'd definitely upgrade him to this hardware. 2) I know that this HN, and people love to be experts and poke at any available hole, but let's assume good intent and not go overboard on the 'dangerous collar' thing. I totally agree that the picture on the website is wrong, but it looks like a render, and as such has probably been farmed out to someone who doesn't know better. Stick this on a decent-quality breakaway collar and you should be fine. (Anecdata: of our two housecats, one will remove any breakaway collar within minutes; the other one doesn't care and his collar only comes off every few months if it gets caught during a cat-on-cat play-fight.) 3) Also agree that there's huge potential in this market for tracking many other things - proven by the success of the Airtag.
