Looking at the Aegis Solo for an extremely durable single 18650 mode. A long time ago I had a heatvape invader mini that was near indestructible and I gave it away when I was cloud chasing with triple battery mods. I am looking to go back to a single 18650 mod and was wondering how the Aegis compares to the invader mini in regards to durability? From what i can find, I dont think Heatvape is still alive.
