Race Face Turbine & Easton Haven dropper posts use the internals from 9point8, the same as in the 9point8 FallLine dropper post So they will have the same issues.
Both of the replacement droppers had issues:
brake stopped working on the two replacement posts.
The bolts rounded off way too easy on all 4 of them.
a crunchy sound at end of bottom travel, on the two replacement droppers, I could also feel, it was rough, like there was crushed metal or sand in there, but the seal was intact.
long very noticeable scratch on the same place on the station.
Foam ring failed on one of the droppers, moved the foam ring to apply
Sram Butter/Slickoleum, but this is not a surprise, they eventually wear out they are not strong, but I was careful, but even so it snapped.
The dropper has a side to side rotating play, which Is annoying, but not noticeable while riding, But the play is bad, play leads to premature wear, noises.
But the play in the station is considered normal, But my next dropper should not have this.
I need to try something different. I desidedon a refund.
There are many options, there is so much I am researching but now it’s the time for dropper posts.
I can’t recommend this dropper due to these issues, the issues came after only a few months, so This is unacceptable.
