I'm a simple guy and once I get something that works well I will run it into the ground until I am forced to get something new. At one point I invested some cash into a Silver Bullet, which I loved but got tired of sending it in to get the connector serviced. I gave up once I got two failures within a 3 month span. Since then I have gotten cheap PVs like the bolt and other clones because I don't see the sense in investing more money into a mod that is just going to fail within a year. I'm asking because I really like the new mechanical Silver Bullet and want to start saving some cash for it but worry that I'm just going to go through the same thing again and again. Is this also what you have experienced and are there some pointers to extending the life of a 510 connector?
