X30 10T engine driver durability/options

So anyone have input on quality and durability of 10t x30 engine drivers?

Oem Iame is like 65$
Nkp is around 40
Righetti is around 30$

So what the durability like on the reproduction drivers? Savings or waste of money?

We all use genuine iame ones locally, the cheaper aftermarket ones we tried didn’t last anywhere near as long.
