Yeah, there was a little while there that QC slipped — but, definitely, there were badly put together lights coming from 3rd party sources — solder over retaining rings, solder instead of retaining rings for example, on lights sold as bargains by resellers.
My impression is that problem is in the past, though some lights will be coming from resellers. I hope so.
It’s a very precarious position to be in, a small business that becomes popular and tries to grow bigger.
