well, just found this thread. When I sold the light, everything was perfectly functioning to my knowledge, I would never intentionally rip someone off, I am not that kind of person. The reason I am not paying him $20, is that when i sold the light, everything was working, after it leaves my hands, i have no control over the situation, I also gave him $60+ off of my asking price in the first place. I also never promised to give $20, I said that I might think about it.Anyone that comes and buys something from me has any and every right to test it out before they leave my house, if you don't do that, and something happens, the responsibility is on you.
Thanks to Weapon X for letting me know this was going on.
