I've seen YouTube vids about it and some other pics, and bought the kit in 650mAh. I like it. Mine doesn't have much yellow, it goes from green, blue, purple, red...
Everyone who has seen it seems more interested in the whole vape thing.
I'm just waiting for someone to earn a "teeth rearranging" and question my choice.
One thing, though. The irridesc is hard shiny metal finish. It seems all the other Halo batteries have this satin finish, almost like a real thin (feels like rubbery?) coating. Makes it much less likely to slip out of fingers.
My black VV is flat and non-shiny. But the Blue VV is great, like a deep finish on a custom car.
Hopefully an exchange is possible. Or you can always swap.
