You made me willing to call out of retirement my old VAMO with short battery. Form factor is nice. And I do not need more than 10W with kayfun 5. But I do not remember where are my two 18350s... When/if I find them, I definitely will try VAMO again.Like the title says I'm interested in knowing if anyone still uses this form factor battery. Yes they are very small, but so are their runtime and amp limits.
