In your opinion are the powerizers a better battery than the imr's?
I just want what will work best.
No, they aren't a better battery. But they are suitable and desirable for use in a Buzz Pro or VV Reo according to Mike of NotCigs. I defer to his expertise and feel confident he wouldn't sell them if there was a considerable risk involved. Nothing is foolproof in the realm of PV batteries, so I've done a lot of reading and tried to absorb the pertinent and relevant information. I am not an expert and don't claim to have any expertise on this subject.
I chose the Powerizers for my personal use but I'm not gonna go recommending them willy nilly. AW IMRs are safer and great performers.
