I got my first mec mod a month or so back, it was the udt-14. I've liked it and had zero problems till now. After the month or so using it, it has now started firing only 50% of the time. It uses a flat spring with a slight bend (to keep it from firing all the time) to make contact from the button and from what it looks like the springs is flattening the bend out . So when you hit the button it's barley hitting the contact. I could be wrong.. So have any of you delt with this thing and a fix?
