I've used that excuse too
How do I use them on my glasses. I frequently can’t find mine and can’t search without them !
I couldn't find my house keys once and was 3 hours late for work. That more than justified it, they were somewhere super obvious too, just tired brain couldn't find them!
I like the idea as well, but I don’t tend to lose things, so not sure it’s worth it....
trying to think what i can use it for , i want a couple and i like the idea that you can change the battery
