Dropper: Fastace, Zoom or Aliexpress E20

[bosbik]

Has anyone used the droppers from Fastace, Zoom or  the Aliexpress E20?
This is for a budget build. Not too concerned about weight but more if the post is "serviceable" and if its reasonably durable with proper maintenance.

I have been running KS dropper posts from AliEx since 2018.  First one was still perfect when I sold that bike so I got another for my latest MTB a year or so ago and its been fine ever since as well.

KS 900i EXA FORM is the best chineese dropper available on Ali. Its well built and last very long without any issues or design flaws.
