I wouldn't flash my mod with anything Cloupor offers. I was a T5 victim, the update fried my mod. I was lucky and contacted cloupor within a couple of hours and they sent me a new T5. Even though it has worked fine After that I didn't think I'd buy another cloupor product. So after a toss up between the T8 and ipv3 I chose the T8 because in the listings it was quoted at firing up to 14v, plus it was cheaper. So far I'm not disappointed. The battery life alone is incredible. I can run a kayfun or blow clouds with the same device!
