A mistake was made fulfilling my order and the nozzles were shipped separately from the hotends. A representative reached out the next day and let me know about the issue and how they had chosen to resolve it.
I had to assemble the nozzles and hotends. No problems yet. I have been a big fan and customer of DUROZZLE for a few years, and I don't think any nefarious motives were at play here. They offered me a generous discount on my next order after I reported that a diamond nozzle broke, and I've been happy with their products. 4.5 stars on this order. I subtracted half a star just for the inconvenience.
