I have an omega and like Pluckit, one of my thimbles had fallen off after a shot. The screw hole was enlarged and would not stay on. I called them mid december and they sent me out a new one free of charge, no questions asked. A week later I received it but it was blued not stainless. I sent it back the next day with the return slip i received with the thimble asking for an exchange. 3 weeks went by with no new thimble. I called and told them the situation and received the new correct one 5 days later. It took awhile to get the whole thing resolved but I can't complain. It cost me nothing and I could still have used it in the meantime with only one thimble.
