Some of the previous posts mentioned the dispay wasn't up to scratch.
So there is a compatibility issue !.
What i'm hoping for is a definite yes or no to the compatibility question. And i don't think i'm going to get it.. This last paragraph isn't directed at you Angibe.
I think the problems with the display generate from people who want something "prettier". The display on the ProVari is extremely functional, durable and reliable. Yes, there are "prettier" displays available. I'm sure the folks at ProVape are aware of them. The 7 segment display has proven to be the most reliable...it's certainly not the cheapest. The military never looks for the cheapest and they still use 7 segment displays in a lot of their equipment.
