personally, for the lot's of adjustable absorber i had repaired. Local absorber is the easiest to repair because it's easy for us to get our hand on their parts. China's absorber though they were a lot of imitation but they still use the twin-tube design which still fairly easy to change it's part. But Taiwan adjustable were miserable for it's build with aluminum and mono-tube design which tend to wear out it's inner wall plus and uneven inner wall means very short service life even after repairing, plus all the parts was custom size which was manufacture in taiwan, so not easy for us to get in malaysia.
If you had a lot's of &&& to spare, aluminum casing and mono-tube sure is a "shinny" choice. if come to money and sense wise, i do suggest go for twin tube design -etc: tein type HA/Super Street damper.
