Got a REO Grand for Christmas. I don't have any 18650 batteries because I elected to use the 18490 AW IMR's that I use with my Provari Mini along with a kick. I know the batteries work and atomizer. The kick is new, but I can't be for sure on it (Never used it until today). Despite my best efforts, I can't get the REO Grand to fire. The fire button doesn't seem to go down as far with the kick in, but maybe this is normal. Any suggestions would be welcomed.
