Just spotted this tiny 10180 stainless steel USB rechargeable keychain light, Trustfire Mini-07.
Fasttech used to have them for around 10 bucks, not bad for a Stainless steel rechargeable 10180 light with a TIR optic, (but they say its discontinued)

while the Trustfire site still shows them in stock, Did anyone have one these? I still use my Trusfire Mini-01 on my key chain for the last 5 years, and its endured a beating and still works great with the BLF Mini-01 driver.
