So, you have an eGo?
Aren't they a 510?
My Halo Elements are 510. I have an 85 mm 280 mAh and a pass through battery. The pass through is great, never runs low on battery.
Both have a manual switch (button) and no cut off until I release the button; which is nice, I can preheat and draw as long as I want to, so I get flavor and vapor without having a HOOKAH! LOL!
My Elements are black w/blue led lights. I don't want it to look like I'm smoking.
I don't want to be hassled or have to explain, unless I feel like it.
Maybe if you let them try a puff off of yours with say, oh mocha flavored tobacco, or Champagne & Strawberries.
Just saying!
That's what really helped me to stop smoking, was all the delicious flavors I could Vape.
I've got a sweet tooth!
