This has been out for some time. I own an XDeep regulator, I was contacted by the retailer, who shipped it back to XDeep, repaired and returned the regulator and included a nice hoody as well.
They were proactive and honest, and it must've hurt them, but I appreciate the approach more than hiding it like the defects of one regulator manufacturer I heard about (the seats I believe) who just silently changed parts when it was serviced next.
They were responsive and acted correctly and the regulator is awesome. Ordered my next one already but the demand is quite high. Have no issue recommending them. It is the manufacturers that don't report or do recalls that you have to worry about.
