If I lost mine - I would be hunting another one down.
The Aeon is not a light you buy looking at the numbers "300 bucks for a 100 lumen light - yea right" (less for the Aluminium one, but the point still applies)
It is a light you buy with your brain, 2 well spaced and very useable outputs, long runtime, small size, bulletproof TI build, flawless machining,
It's a "lifetime light" a quality tool you purchase, with the intention of using it, then handing it down to your kids, not overly pretty, or super bright, but simple and functional and will keep doing what it was designed to do for a long long time, picking up little marks and scars from its owner over the years, much like any other good hand tool.
Mine is not my primary edc, it is my always with me EDC though, it hangs on a lanyard around my neck, unless I'm in the shower or a swimming pool, it has been there for over a year, and is on it second battery, not because the first one died, but I needed a CR2 for my laser pointer, so the aeon got a new one and the laser got the lightly used one.
After a year of edc the brass bits have formed a patina, and there is some dust in around the lanyard ring hole.
Other than that it still looks brand new.
If I lost it there would be a WTB posted very quickly.
