Lately I have been caught up in the dna 30 devices, kayfuns, drippers and everything regulated. My reo was not working, the button was sticking and making constant contact with the battery. I planned on sending it in but cuz I am lazy and don't like to deal with returns and warranties and what not I moved on. My love for my reo brought me back to it. I cleaned the switch with alcohol and most importantly the hole the switch goes in and....... I am back in business, works flawlessly. I have fallen back in love with my reo mini!! Life is good again
