I've been making sure to only buy CMB (CM Becker) as they have been working perfectly for years, with no issues. Never seen or used any of the other brands you mentioned.What brand of plastic qd’s are better? I see so many different ones to choose from, Onebom, Petra, CM Becker, JanSamn, etc. etc.
I've had one (black) liquid QD that was unbranded. It disintegrated when forcibly removing it after having pushed it onto the wrong post, the gas one. The collar separated from the rest of the QD body, spring came out, etc. I can't really blame the QD for that. It took a lot of effort to get it off.
