Honestly I like key holders as I find myself carrying a bunch of keys that unless they’re in a holder, they have a tendency to jingle as I walk. So I actually had a cheap Chinese import key holder with attached Tile but I managed to tighten and break a screw on it. However it lasted a good few months and I definitely see the utility of them so maybe others do too.
So it’s a keyholder with a Tile Tracker and LED torch built in. Micro USB port for charging. It’s cheaper to buy a dumb key holder and attach a Tile but this has the advantage of not having to mess around with lithium coin cells when the battery dies. This is kind of a niche purchase but the non-lightning deal price was £55 so this is a substantial saving.
