It's like buying counterfeit stuff from China, it might LOOK the same (well, at least similar) but that doesn't mean it is the same. It doesn't mean it's a bad part, but, be aware of what you're getting into before blowing a bunch of coin.
I look at it this way. My son owns a filament printer and a resin printer. If they don’t last but 5 years I’ll reprint a pair every 4 yrs, 11 months.
Minimal coin needed.
