Hey EasyE, Haven't seen you in a while, welcome back. Sorry to hear about your troubles. I usually check The resistance on my attys when I rec'v them so that if they are DOA I can return them. I like using LR510s from puresmoker (Have not had a bad one yet). However, to get them for about $5 each you have to buy 25. Good luck finding an atty you're happy with and maybe pick up a 5 pack of cartos as a backup.
